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

Anime is hand-drawn and computer animation originating from Japan.
Anime; the one thing that gets us closer to each other and brings us together.
All spoilers must be tagged!
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, ...).
This was going to be my suggestion, Ghibli has made some really phenomenal shows.
Does she have any specific interests? I guess if nothing in general, she might enjoy something like Spirited Away or Spy x Family?
Maybe something chill and comfy like Yuru Camp ?
Spy x Family
Cardcaptor Sakura
Bocchi the Rock
Nichijou
Spirited Away
Toradora
Keep Your Hands Off Eizouken
Dragon Pilot
Komi Can't Communicate
Violet Evergarden
Your Name
I'd veto Spy x Family and Violet Evergarden; the violence they have is quite brutal, and the themes I think are fairly adult.
I don't want to get hurt so I'll max out my defense AKA Bofuri
Another vote for Bocchi, it's an awesome and inpsiring anime. Plus, I think it could be empowering to a little girl to see an all girl cast kick ass at being rockstars.
The only con I can think of are a few adult gags, though they aren't super offensive. Most kids shows I warched growing up had adult humor that flew over my head, so it should be fine. Just something to consider.
Ancient magus bride was a cute fairy tale type anime
Non Non Biyori, Mitsuboshi Colors, and K-on are pretty light-hearted, slice of life, comedies that would all be good
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.
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
Azumanga Daioh is where it's at!
When I was 8 years old I watched a LOT of Doraemon...
I'd suggest "How to Keep a Mummy" from a few years back. Super cute and wholesome.
Have you shown her any of the studio ghibli movies?
Right, yes, I forgot to mention, we watched My Neighbor Totoro & Kiki's Delivery Service. I should probably try to show her some other ones. Good call!
You know, I was half expecting people to troll and suggest something like "Made in Abyss".
I just finished watching this, NO WAY DO YOU SHOW THIS TO A YOUNG KID.
