I guess do you mean with the cartoonish demeanor or just boxing ones as a whole? Have seen a few on playstation systems like knockout kings but they try and be all serious with it.
Shadow Boxer maybe. It's an arcade boxing game with the same kind of format as Punch-Out but not as easy.
If you want something a little more realistic, there's Undisputed; a Fight Night clone currently in early access on Steam. But it's not remotely like Punch-Out other than being a boxing game.
I've played so much Punch-Out, I tend to think of it more like a puzzle game. Especially Super Punch-Out since your opponents don't even seem to randomize their patterns like they do in the original NES one. 😅
