OP here (though I don't claim any special insight, as I said).

It would be interesting to consider the differences between the Charlie Brown and Arthur Dent character archetypes.

One difference seems to me exactly the undying earnestness and optimism you mentioned: in a way, Charlie Brown and other American characters like him are simply not touched by failure (even if bad things happen to them), because of their optimism[1]. This makes them lovable: we appreciate them for this quality that we (most of the audience) do not have.

[1]: (or lack of self-awareness, in some other cases mentioned here like Homer Simpson or Peter Griffin)

Arthur Dent, on the other hand, is not gifted with undying optimism. He's constantly moaning about things, starting with his house and his planet being destroyed. This makes him relatable more than lovable: he's not a “lovable loser” (and for the right audience, does not seem a “loser” at all), he is just us, “my kind of guy” — we feel kinship rather than appreciation. We relate to the moaning (if Arthur Dent were to remain unfailingly optimistic, he'd be… different), whereas if Charlie Brown were to lose his optimism or if Homer were to say "D'oh!" to complain about big things in life rather than hurting his thumb or whatever, they would become less of the endearing American institutions they are IMO.

I would not say that Charlie Brown is untouched by failure. He does descend to the depths of despair. But some how rises from it to try (and fail) again. This trope is seen best with Lucy pulling away the football every time he goes to kick it. Even though he knows he's failed every time, he talks himself into this time being different.

This does not contradict your overriding point, just adding nuance to the claim he is "simply not touched by failure".

I suspect that one difference that gives the impression that the characters in Peanuts are "untouched by failure" is that for the most part they don't have real character arcs. Once their archetypes are established they stay the same. Combine that with being the longest running comic written by a single person of all time and it feels like nothing ever changes.

That's not a critique - being a comforting source of unchanging familiarity is part of the point of a newspaper comic. But it is very different to H2G. Arthur Dent might be a bumbling failure who is flung around by forces out of his own control, but his life still changes and he still changes. He still grows a little bit as a person.

But Charlie is a fool, a half-moron. Arthur is not dumb.

Homer used to complain about the big things. He tried to kill himself in the third episode due to losing his job. The first 2 seasons are honestly comparatively depressing with some of the heavy topics they touch on.

The Simpsons just leant so far into 1-note characteristics that they became caricatures of themselves - and the term Flanderization was born.

OP, if you’re still lurking, are you familiar with the Flashman series? I feel like it falls somewhere between the poles here. Either way, would highly recommend it to anyone who likes Adams, history, learning or reprobates.
