If you have a switch New super Mario bros U deluxe and Super Mario 3D World, both let you play as Peach and Toadette and you can do local co-op so you and her can play together.

I think Tchia may be just what you're looking for!

There's that Disney dream light game or something like that, definitely seems child friendly.

Contrast on Xbox market was awesome. Really fun platformer that has an amazing soundtrack too

Hey!

It's not coop, but I recently played "The Big Con" (with Gamepass) and it's more of a fun ride with an easy control scheme and decent puzzles. While the FeMC isn't the classic "strong female lead", she is a teenager growing up and develops throughout the game and it's story.

I found it very funny (your daughter might not get every joke, tough), depicts some good topics (trust, family and responsibility) in a very lighthearted way with a cute art style. :)

Ms. Pac-Man, but of course!

There's always Animal Crossing and its many sequels... you're not obligated to play as a female, but it's at least an option. Metroid has a female lead, but those games are probably a little beyond your daughter's grasp at the moment.

Gianna sisters: twisted dreams

Alba: A Wildlife Adventure You play as a young (7-ish years old?) girl exploring a Mediterranean island, taking pictures of cute animals and saving a nature reserve. Very child-appropriate and a joy to play. Highly recommended!

Roughly what age are we talking? The list you linked is accurate and pretty much all the mainstream ones. Also,

• Telltales The Walking Dead

• Minecraft Story Mode

Giana Sisters as female C64 clone of Mario Bros.

If you're okay with some very black comedy (all spoken-aloud, nothing shown) and the occasional blood splatter when you get shot, the Portal games are good. The villains are robotic turrets with machine-guns that are defeated simply by tipping them over - so while they're acting in very violent and lethal ways, the player is just teleporting around and nudging them over to fall down onto their side. But I remember my kid being very offended when GlaDOS called the player character fat, and later reveals she mass-murdered a building full of scientists using nerve-gas.

They're not particularly old. There's a few games as recent as this year there. But then, can you really trust the quality of a list that includes 'Laura' (sic) Croft?

What platforms do you play, and how old is she? Because there's no point in us recommending particularly grisly PS exclusives like The Last of Us Part 2 if you're an Xbox player with a 6 year old.

Some of these might be a little more like 8 than 5 because they have storybook-scary but still mentioning for you to have a look and decide.

Lost Words - Beyond the Page
Unpacking
Epistory - Typing Chronicles
One Step from Eden
Wargroove
Tsioque

Technically not female lead but kinda close and definitely age-appropriate:

Chicory - From creators on Wandersong + Celeste. Not positive your character is canonically female but let's just call it very plausible and you are filling in for the titular character who is called "she".
Donut County (technically the male racoon is the main character but the only human and next-most important character is female)
Journey (likely canonically no specific gender but great game, no dialog and could easily interpret as female if you choose)

Not what you asked for but maybe consider:

Beglitched - No human characters other than the player, puzzle game with pink and purple hacker aesthetic.
Lovers in a Dangerous Spacetime - Androgynous animals and humans pilot a wacky ship in 4 player co-op lots of hearts.

Tearaway Unfolded on PS 4/5.
