What can my 11 year old brother watch?

No sexual themes (that he would pick up on) and no extreme violence

He's watched a couple studio ghibli films and I got him a bit into one piece

I was thinking maybe mob psycho first season

Edit: not watching past the first season of one piece (doubt he'd be interested anyways)

It's less about my brother and more if my mom sees us watching it 🤣

Top choices so far: mp100, frieren, spy family, older anime similar to pokemon, maybe some dragon ball, more studio ghibli films, hxh up to chimera ant arc
