I think it's a pretty heavy load roleplaying another race well, taking into account their outlook, longevity, size, shape, history and so on. So I just play human and engage more with class and background. I don't care much for racial features, they're nice and all, therefore I'm happy to play human.
Back in the day humans had:
1E, no level limits, duel classing, bard
2E, ditto, but bard changed to open class
3E, extra skill and feat
4E, floating +ability score, extra skill and feat
5E, global +ability scores / or floating +ability score, extra skill and feat
BG3, floating +ability score, extra weapon/armour proficiency & carry weight. No idea why that last feature, maybe it's something similar to dwarves as some humans are also as hardy?
