@2tone, Spiritfarer (https://thunderlotusgames.com/spiritfarer/) is pretty dang good and visually would be awesome for a younger kid. Visually it's probably some of the best to watch. Just be aware it's thematically about death. It's very sweet and wholesome, but you might get some heavier questions about it. There's a lot of stuff that might go over her head but will gut punch you. Could be a great way to have those conversations but, you know, sometimes it's a long day.

On the other end of the spectrum, overwatch is free to play and the roster is crazy diverse. That's actually the game where it "clicked" how important that was for me. Games in a rough spot, but there's still fun to be had time to time.

edit: if you want to give em Nightmares, Prey (2016). Pro: A strong female protagonist in a STEM field! Con: They'll never go into a STEM field because they think you'll be eaten by monsters.

edit: Maybe fallout 4? It's Bethesda so the combat animation is about as visceral as a cartoon. An RPG could be fun because you could ask them where they want to go etc. Plus: It's got a dog.
