Mine is that at my age (barely made it into Gen Z on the old end) I just found out today that a Bo Weevil is an insect (beetle) and not some kind of mole or similar rodent.

I am not sure you were as wrong as you think - see definitions 2 and 3 here
Usage of words shifts and sometimes expands over time.

I would personally definitely interpret “apparently” and “plainly” differently - “apparently” to me is “the evidence so far does seem to point this way, but I am not necessarily convinced, or have strong feelings either way” vs “plainly” is “the evidence is clear, I am convinced, and so should you be” - although obviously context would matter as well and could alter this interpretation.
Edit: even your example usage “I’ve been trying to get myself out of that habit, but even judging from my comment history, it’s apparently pretty hard” - to me the usage of “apparently” here indicates similar tension and/or contradiction, in this case between belief/intent (I am trying to stop the habit) and evidence (but my comment history shows otherwise) - it wouldn’t work quite as well with “plainly”
It would work with “evidently” but carry more of a connotation of confirmation and shift the emphasis (I am trying to, but its hard as confirmed by evidence) rather than contradiction (I would like to think I am doing it, but evidence shows otherwise) - of course you might have meant it either way (or even neither) - I am just saying how it reads to me.
