Sibling has a couple of suggestions.
One is "Welcome to Demon School! Iruma-kun" I have only watched some episodes here and there (my sibling has watched all of it) it is rated a bit higher in different countries but my sibling says that it should be fine if you are watching it with them. There are some mild sexual topics and violence but it should be fine.
"Yokai Watch" is for kids, it's PG in most countries and is similar to pokemon. I haven't watched it myself (maybe the first episode years ago) so don't have much to say about it. XD;
"D.N.Angel" is also a suggestion. I did watch it a veeery long time ago but don't remember much. My sibling say that they watched it as a child. It's a romance though so it might not be fun. XD
"Magical DoReMi" is for kids too. It's a magical girls one so it might be fun. 🙂 I think I watched a bit of it too but I don't remember anything from it. XD
"Little Witch Academia" is also for kids, it's apparently very popular right now. I haven't seen it at all. or heard about it. XD;;
My sibling says that the ones they recommend the most is "little witch academia" and "yokai watch".
