Just to add my 2 cents.
Let reverse the question, why would you ever play a human in a fantasy setting, where you could be just about anything?
Instead of the fantasy classes do you pick "commoner" or "expert" as your class (cause thats what you are in real life)? Do you use your own stats for your character?
F no! You choose something fun and exotic that you can never be in real life.
Do you play Bob the level 4 Human Accountant, with average stats, who can do your taxes?
Or would you play Xragis the Kobold Master Transmuter who can turn his allies into T-Rexes and foes into rabbits?
I guess some people just like vanilla and only vanilla.
I've played PCs like Bob. The guy just had a normal life (not an accountant but a cook) who would like nothing better than to go back to the simple life. Unfortunately he got caught up in something and had to become an adventurer. Throughout his career all he wanted to do was settle down and open a restaurant.
Because of the way the game works he was a cleric (and the Chef feat from Tasha's would have been perfect), but at heart? He just wanted to open a chicken shack. Maybe a small chain of restaurants. I played it mostly for laughs, but playing someone who would rather do anything but risk their necks adventuring (but does it anyway without excessive whining because it's necessary) is a pretty common fantasy trope.
Since I want to contribute to the party and the way the game works I'm going to have character levels, that doesn't change the mindset or approach of the PC.
But no, I wouldn't want to play Xragis. He sounds silly and has no grounding in a reality I could relate to. YMMV.
