I'm a GURPS fanboy. Complexity is determined entirely by how many rules the GM and players agree to - I've got a player with dozens of skills and several wonky abilities who plays side by side with an 8-skill player. They both do well, and both have what they want - one character is just more detailed than the other. The trick with GURPS is to pull in the bare minimum of rules that you need for the kind of game you want. If you don't like how a rule works? Swap it out! I've enjoyed the Ironsworn line too, for a different feel. That's a much less complicated system that can also be played GM-less, it works narrative elements into the engine - the story dictates how the rules apply!

Unless you are uncomfortable with the situation and it ruins the game for you, sure.

The burns, did you fix the burns?

"Um, I think you're cute!" 🥺

They weren't too bad, and they were on his other hand, so they didn't even get in the way later that night

Heaven forbid I try and get my players to actually roleplay in this roleplaying game.

If roleplaying ruins the game for you, maybe a roleplaying game is not for you

"How did you know I like compliments?!?!?"

There’s a major difference between “roll at least a 16 and you’ll have seduced the guard” and “seduce me to seduce the guard.” Different people are comfortable with different things. If you’re fine seducing your DM, cool. But I certainly wouldn’t be.

Maybe charisma builds just aren't for you.

That should only be required if what you're trying to do would have a higher DC than you could possibly roll, but the DM humors you by allowing you to try convincing them anyway. Or that has been pre-agreed in session zero because the group is all theater/improv nerds or something.
