Animes with good values for kids?

What I love so much about anime is that, unlike cartoons that are often just about superficial entertainment, anime really tries to teach values—like friendship, never giving up, and perseverance. Now, I want my six-year-old kids to watch anime too, not just for entertainment but also to learn something along the way.

What are some good anime shows that teach these kinds of values but are still appropriate for children?

I know I watched a lot of Dragon Ball when I was that age but I‘m not sure if that was appropriate lol
