Coming from my background as a game designer, I'd try to make sure to have something for everyone, so I'd probably offer a widespread selection, but honestly, the ones I have in my latest story are the ones I'd probably start with.
Humans, Bunnies, Cats, Elves, Dwarves, Dragons.
And then I'd pick each of those 6 types, and divided them into the furry version and the anime-version. Cat-people vs Catgirl, Antropomorphic bunny vs Bunny-boys, etc.
Oh, and I suppose I really should add stuff like Orc/Goblins, Kobolds, because there's certainly a huge amount of love for goblin-moding this day and age.
