Wedding stats to races is in fact the only thing that actually does make sense, though of course it isn't political these days, nor is it newbie friendly. But if you step out of D&D for a moment and consider, say, Star Trek, then please don't tell me that you think Klingons and Humans should have the same base stats. Please don't tell me Klingons and Ferengi should have the same base stats.
Just a rapid research and I can find that in the last ttrpg about star trek species have stat bonuses too, but these can be easily compensated by "environment", "upbringing", "academy" and "career events", making them just a drop in the ocean between all the stats you can distribute on your character.
If 5e implemented such an elaborated system to make every class work thanks due to bonuses coming from class, background, ideals and whatnot, something that has been implemented by Pathfinder2ed, sure racial stats would be cool, but at the moment they are just a nuisance and an arbitrary limitation.
I suppose, at least you're honest about hating world building affecting combat for the sole reason of minmaxing. You'd dislike Warhammer so much.
I should get something about the warhammer world, but I've seen that there are many different systems that I honestly don't know which one I should pick. I honestly don't think that "worldbuilding" means solely what you are saying. There are various ways to build a world, and the world building in 3.5 (hard dungeon crawler) is different from the world building in 5e (narrative oriented), which is different from the world building in world of darkness (hard narrative), or any PbtA (hard narrative) for the matter.
EDIT: just narrative for WoD, because PbtA is far more narrative.
What I'm saying is that the philosophy of "every species should be equally good at everything" would... well, not get you a very positive response. It's the exact opposite of what people like. So I'm here now, imaging future fans bragging about how the franchise finally moved on from that limitation. It should be funny, but I can't, because that would never, ever happen. They've got their own issues, but they're winning on this point. If you say "x are trash because it's not meta", prepare to be swarmed by angry simps.
