Maybe something chill and comfy like Yuru Camp ?

Does she have any specific interests? I guess if nothing in general, she might enjoy something like Spirited Away or Spy x Family?

Azumanga Daioh is where it's at!

K-On!, Laid back camp, Sailor Moon, ghibli movies as many have already stated, all good to try

Angelic Layer, Azumanga Daioh, Fruits Basket, anything Studio Ghibli, Princess Tutu, maybe Spy x Family.

BoFuri is cute and sfw, no real violence.

Kuma Kuma Bear falls in the same area.

Many of the Ghibli movies should be perfectly fine (My Neighbor Totoro, Whisper of the Heart, Kiki's Delivery Service, Ponyo, The Secret World of Arrietty, ...).

Bocchi the rock

Majo no Tabitabi. A very enjoyable magical adventure. Episode 8 has a jump scare that she might not like, so skip that one or watch it yourself first and decide. The episode itself starts with a warning about this so you don't need to remember which one it is.

Somali – another magical adventure, I don't recall it containing any scenes that a child would be uncomfortable with.

It has some fight but maybe she'll like CardCaptor Sakura

Ancient magus bride was a cute fairy tale type anime

I'd suggest "How to Keep a Mummy" from a few years back. Super cute and wholesome.

I don't want to get hurt so I'll max out my defense AKA Bofuri
