Anime to watch with my 12 year old sister?

My only intel is that she likes Legend of Zelda, so I was thinking Frieren, but I haven't watched too much anime. Would love some recommendations, thanks in advance!

Edit: Thank you all for your wonderful recommendedations! We are watching Frieren right now and after a few episodes I think it's perfect. After this I have a list of new ones to look into to line up another based on below suggestions.
