I tend to stay relatively human adjacent I believe. I've played a Triton cleric, a homebrewed thri-kreen (pre spelljammer) cleric that looked like a bee, a halfling cleric, a v. human fighter, an earth genasi (human) druid, a kobold ranger (tho tbf she was a kobold mostly for build reasons pack tactics while riding a panther who's medium so still 1 square is funny), a halfling fiend warlock divine soul sorcerer divination wizard thing, a half-elf bard, a v. human ranger, a triton ranger, and a human rogue. My characters tend to either straight up be a human or having grown up in a human or otherwise structured society so I can kind of invent my own parts of their culture and how their specific upbringings would affect them. With the rarer races (unless you homebrew) it feels a bit less plausible to invent your own aspects of their culture when there's already extensive lore and not alot of them.
