While a simple accident is still the most likely theory, the surprising location she was found in does raise some eyebrows. Frankly, I cannot see how anyone can say that suicide is unlikely, but maybe it is just the occupational bias in my case.
I see several factors in this case that make the hypothesis of suicide more likely than in a random case: in the days leading up to this she was reaching out to strangers with her life problems, history of depression, probable big life changes coming up, being a kind and sensitive person, being somewhat of a perfectionist, possible history of eating disorder, returning to an area she loved, saying that she will be out of touch for a while and being vague about her plans, stuff in her personal IG history like last 3 mentioning death and last 7 not having a human on them etc. No, relatives are not usually the first to notice and people with concealed depression might be even more likely to commit suicide than people with MDD. And even in any random case without any red flags suicide should not really be ruled out "just because".

With that being said, accident is my 1st pick, and I hope the phone history & autopsy & exact locations might confirm one possibility over the other. I' currently have a hard time to understand how and why she ended up at the location she fell from.
Choosing your post to respond to, mostly because you cover so much territory, so it's a one & done. Working backwards, kinda.
1. I'm very unconvinced her phone records, if ever made public, will resolve much of anything, unless perhaps via GPS, the route (s) she took.
Consider. Let's say she took tons of photos. What would that mean? That she was happily exploring? Or that she was documenting her last steps before she threw herself off a cliff? Or, she didn't take many if any photos at all. What would that mean? That she didn't bother because she was so thoroughly & contentedly in the present as she adventured? Or because she had chosen a challenging route & was intent upon it? Or, because she felt liberated & felt no need to document everything for Dan? Or, because she was so absorbed thinking about what came next, which was her plan to throw herself off a cliff?
2. One objective truth photos could help reveal is the route (s) she took. But the factual again ends there. Leaving aside your specific list of reasons why you wouldn't summarily reject the possibility of suicide (I wouldn't/didn't either, but for me context is always everything). And more as a response in general to posts related to the possibility of suicide.
Again leaving aside other various bits of context, what seems to be a common denominator is questioning why ED ended up off what's perceived to be a beaten path & higher up & in a place many seem to believe was a risky (fill in synonym blank) place to go.
The *factual* basis for that question I see is it's based on what Dan said about ED. That she was adventurous, but didn't take unnecessary risks. That she didn't go off the beaten path if there was a beaten path to be had.
But that assumes Dan knew ED well enough to know perfectly & inevitably what choices she made & how she adventured when she was alone. I don't assume he had that knowledge, other than in a most general way.
Maybe because I don't, as an isolated factor I don't find it mysterious or of concern, or an indication she was unhappy much less suicidal, that she fell from an off the beaten path, higher up than expected place, the exact location apparently still tbd.
From there to what can only be speculation. Nothing wrong with that, it's one of my favorite hobbies, but it ain't the same as facts.
Yes, it is factually accurate that a loved one can be the last to know. It's also true it is simply impossible for anyone outside another's relationship to * know* what's going on within it, much less peeps who never met either of them. Speculating, then, I don't think Dan would be in the category of last to know. Unlike most of us, I imagine, Dan & Esther were largely very much together 24/7 for years, often in a very very small space. Each knew the other had been diagnosed with clinical depression at some point. Both spoke openly about their feelings, including on SM.
If anything, one impression I get from their last known communications is that Dan may not have always given her enough space.
Nov 21. 1:11pm. ED to Dan: "Love you so much. *advertiser censored*. thank you for encouraging me & giving me this confidence."
Next day, at 3:31, ED to Dan. "Can't wait to read all your messages. thank you. *advertiser censored*....."
She's chosen to go off by herself, and she's been in recent touch. Why flood her with messages? But....as with anything speculative, that take is wildly subjective.
The actual facts are that she was regularly in touch with Dan. She told him her plans. She told him she loved him, and that she was having a good time.
She did caution him about possibly bad cell reception. Dan doesn't question why she did that. But, it is in the speculative range of possibilities that it didn't occur to Dan or he didn't want to say to the public that perhaps ED had decided she really did need some all alone time. Or, who knows, that she was considering going off the beaten path & higher up than he would approve of & she didn't want to hear his thoughts about it. Or she wanted to surprise him with her accomplishment after the fact. So, so thoroughly back in the area of speculation.
As this is painfully too long already, to skip to an end. I haven't see those references to death on her SM. There isn't any evidence she had an eating disorder, and there are *plenty* of health oriented peeps who don't that are extremely hard core & diligent about their eating habits. She *seemed* to be making a major life choice, which sure, can be stressful, but even if that, stress doesn't even equate to unhappiness, much less anything more dire.
Long story long as humanly possible. It's not from rejecting suicide out of hand or "just because" that I have, but because I don't believe there's evidence to support that theory, and again, neither apparently does anyone closest to her or the investigators themselves. Absent that evidence somehow showing up in an investigators' report, even if their conclusion is otherwise, accident it is IMO. (And BTW, having been on WS for many years & alive for decades longer that that, I'm plenty aware peeps come to their own conclusions in their ways for their own reasons.
