Ruroni Kenshin is a pretty dark historical war story when it gets going fully, I really don't think a child should watch that. The beginning is intentionally deceptive for narrative reasons. The newer one is a lot more upfront with it.

Dragon Ball is extremely inappropriate, If I were in that position I would not want my daughter to watch that and mimick ANY of the behavior Bulma commits. Especially with Roshi. The super fanservicey stuff gets cut off around Z or slightly before, but OG will shock you if you haven't read or watched it in a while.

For my pick, it's hard to list anything super similar minus what was already mentioned. As a cool anime for female empowerment I'd pick Bocchi the Rock, anime about a girl overcoming social anxiety to fulfill her dream of becoming a rock star. All female cast pretty much, no fanservice, pure comedy, good story, and rockin music. There's like one or two inappropriate jokes that'll fly over a kid's head, but most children shows in America had worse.
