What's the point with that quite lackluster story in Endwalker?

My question to them would be why even try aim for that? Maybe it's "scary" to a being which isn't immortal with creation magicks, but I find it weird to aim to portray it that way, as if they're wrong simply because they're a different type of being - perhaps you could convey that they're a bit strange or otherworldly by human standards, such that we'd struggle to live that way, but to me that's something different from setting out to make them scary. And frankly, that's how SHB dealt with it.

Also, they didn't aim to do this with the dragons which, sure, have some "scary" aspects to them - no one is sitting here saying because Nidhogg went off his rocker (for understandable reasons), that dragon society needs to be reshaped from inside out, and their kind wiped out to something less "scary". Also, there is a sidequest in Elpis that does ask you to opine on how you find the ancients, giving 1) as gods 2) not too dissimilar from us (sundered) and 3) inscrutable. So clearly it runs a gamut of options, all of which I'd argue are somewhat true.

Honestly, the issue with the alternative approaches I've seen recommended is that they buy into the premise that the ancients had to be "scary" or needed to have some critical flaw, when they could just as easily have had the Sundering result from an accident or (orchestrated?) misunderstanding, instead of fixating on justifying it. I think you came to a similar conclusion here.

Exactly. And to me, it's no less innate to them than a dragon's great powers are. People keep trying to frame this with us as humans as the gauge of what's "natural", but in the context of the setting, these powers are natural and innate to them. I'd speculated in the past that maybe her faction had misdiagnosed the origin of the crisis, which would be understandable if you just saw creation magicks run amok, which I think would've been a more plausible motive than what they went with.
