Anime for a 10 year old

My sister is 10 years old and is interested in anime. When she was around 7-8 I showed her my neighbor Totoro and she liked it

Now at school kids are talking about JJK and stuff like that. Personally I think JJK may be a bit much for a 10 year old

Yesterday I showed her Spy Family and she liked it

Are there any age appropriate shows I can show her? Also she’s not a girly girly at all, so the cute girls do cute things stuff isn’t cup of tea.

Side note:

It’s funny that I’m being so careful about this, I’m 29 (I know massive age gap) and I remember watching Air Gear at 11 years old like “holy crap boobs”.
