Like Legend of Zelda, everyone is referred to as human, but humans from Hyrule have pointy ears:
(I also like how Conan does it, the cultural difference between an Aquilonian vs Zingaran vs Hyrkanian are distinct, but they're still all human.)
Non-Hylian humans
A Gerudo human, almost all female they kidnap other humans for their seed.
Fallout had a nice way of just saying "Being a skinny agile guy is a trait a human can take". Any piddly +/- stat change could just be represented by such traits to take.... or you ignore it and stat distribution is your justification of why your human is 4ft tall and 4ft wide with a 4ft beard.
Say if it was for D&D, then the "extra feat humans can take for being human" would be what you can consume to pick up the "you're a human from a highly magical society... which tends to have pointy ears" feat.
If something's going to be a separate race/species, they should feel significantly different. Lizardmen & snake people, bee girls & beetledudes, birdmen, robots, that's the kind of distinction I'd want for a not-human PC race.
Elves and dwarves are fantasy staples nowadays, but I figure if you had characters who LOOK like elves and dwarves its enough to appease the fans without calling them elves and dwarves and live for centuries.
