What do you look for in an Anime Protag?

When finding new anime what qualities do you look for in the protagonist(s), personally i tend to look more towards the quieter kind characters, or the ones with a dark past

If I'm supposed to admire them or something but they're just overpowered and that's just it, like it's a power fantasy for people I guess? I mean some characters are overpowered but they fight impossible odds (Guts) or fight powerful foes (Kenshin) or their strength is funny (Saitama) or it's part of the plot (Aang). But then some are just ridiculously overpowered for no reason other than they are the protagonist so they must be the strongest and they're likely the protagonist because they are the strongest. Protagonist need to be stronk and be able to beat everyone right? Even worse if it gets to mary sue level... Also if they're annoying or unbearable... ughh... sorry I did the opposite of the thread by stating stuff I'm not looking for but I found it easier to word my opinion this way. I don't look for particular stuff in a protagonist, they can be lots of things.

I usually like a protagonist that actually sticks to their morals and ideals. Ironically I admire it more when they go off the rails yet somehow always find a way back to themselves cause that is obviously much harder yet more amazing to do in my opinion.

Reasonably skilled when starting off, not cartoonishly perverted, not too much of a goody-two shoes, doesn't have a harem, doesn't have too much of an obnoxious personality, strong-willed, confident, committed, principled, but not stagnant.

A thoughtful character. One who thinks about his actions and can reflect on their behaviour. Doesnt take things on face value.
