Kid-friendly dubbed anime

I need to find ideas for some kid-friendly dubbed anime (preferably on crunchyroll). Niece and nephew are really wanting to get into anime but I'm struggling to find decent shows they can watch, they're 9 and 7. One is obsessed with one piece despite never having seen it, bc it's a 14 I think, but they're currently enjoying my roommate is a cat, I've shown them some Ghibli films and they liked those too. I don't mind if animes have some swearing but I don't want a lot of fan service or sexual jokes/situations which there's a lot of in anime, some violence is okay but I'd prefer a lack of gore and/or extreme violence. They don't necessarily need to be aimed at kids, just appropriate and wholesome.
