That'd be a fair version of 'meaningful' in the context of the definition of balance that I find most useful. I'd be open to a broader take on meaningful, taking player preference and potential impact and I guess "framing" into it, as well as actual, final impact.Compelling play rests on asymmetry of choices. Every choice a player makes should have an impact on the play space.
That's a familiar phrasing from outside the hobby.Game balance for me is all about establishing equality of opportunity, rather than equality of result.

Balance applies at both levels. You can give the players many meaningful & viable choices at chargen, and many more (typically more granular and situational) in play. And, yes, a game can contain one choice that's arguably better than (as opposed to strictly superior to) another as long as both remain viable. And, yes, especially in play there may be some non-viable, even disastrous, choices available, and a cloud of 'chaff' meaningless/useless choices as well, if you like.Still for the most part I am wary of giving too much weight to decisions made in character generation. I want the heart of the game to exist in decisions made in the heat of the moment. My preference is for other decisions to impact the sort of decisions made in the core game, but not to exert undue influence on the results.
That's one of the classic conundrums.I really dislike RPGs where the classes/characters all seem the same but the more variation you add to PC abilities the greater the potential for power imbalance. I actually have found 5e to be somewhat of a "Goldilocks just right" of variation vs. balance.

Personally, I'm willing to cut a game a lot of slack in the 'meaningful' category, since subjective elements can make some choices more meaningful to some gamers than to others, but you clearly don't feel that way, so let's consider Campbell's thought, above, about each choice /making an impact on the play space/. If you really did have some choices that had no impact on the specific experiences of play, they'd be meaningless to that level of rigor (they might be very meaningful to a given player, and it doesn't hurt to let such players make those choices, it just doesn't contribute to, nor much detract from, balance). D&D hasn't ever been in danger of perfect balance, but that failing is not for a lack of choices or for a lack of meaningful differences among them - it's the presence (even prevalence) of non-viable choices 'traps' or (if no one's really tempted to take them) 'chaff.'
Yep. If you can tolerate or compensate for the profound imbalances described in optimization Tiers - playing all the same Tier, for instance, or playing E6 where the problems are less profound - 3e's wild customizeability is still pretty awesome. I love to play it when I get the chance, but I'm not really up for trying to run it again, for that reason. Still, it was a wonderful step forward from the tightly class/race- bound classic game.3E had great variation and possibilities for character optimizers (which I enjoy to a certain degree) but the power gap between clerics, druids, wizards and everyone else became so gigantic that I found higher level games unsustainable.
4e was better-balanced than other editions of D&D, but relative to broader comparisons or theoretical ideals of balance, not so much. Not that it isn't fair to call it 'very balanced' in this context, just, y'know, perspective.4E was very balanced, but the classes felt so similar to me that I got bored.

No, it's not. And, it would be ruinous to balance if they were to contribute /identically/. But it's perfectly reasonable to aim for them each being viable within each pillar independently of the other. There's a good reason to aim for that, too, as it Empowers the DM to run campaigns that emphasize the pillars differently.The three pillars of D&D are combat, exploration and social. It's not realistic to expect all classes to be able to contribute exactly equally to each pillar
Maybe not incumbent on RPGs in general (and this is the general RPG forum), but I want to point out that 5e, in particular, has among it's several impossible goals, supporting the full range of playstyles supported by each past edition...I don't think it is incumbent on the game rules to address the fact that some DM's emphasize one pillar over the others.
... and, I'd presume, more besides.
