Florence - it's short and sweet.

I'm currently playing Research Story, that one is pretty cute. There are romances. I don't know about combat since I haven't gotten that far (just a few hours of play); it doesn't really seem like there will be combat, but there could be.

I'd also recommend Apico, Mudborne, Littlewood, or Fields of Mistria. I'm sure I'm missing a ton. I think Steam has "Cute," "Romance," and "Slice of Life" tags if you wanted to browse those on the storefront.

If you’re open to the idea of ditching a Microsoft product, I’d suggest Vintage Story as a Minecraft alternative that I think has a nicer aesthetic. It’s meant to be a sort of slow, “grindy” game, but if you sort of rewire your thinking to it being a slice of life game, akin to Stardew, I think it’s very fun. Fair warning the early game can be very punishing if you’re brand new to it, so explore the world and difficulty setting when you make your first save.

Somewhat cozy game with a femme lead I’m excited for is Cairn. It’s got a demo at the moment, but I’m very much looking forward to the full game. It’s technically a survival game about rock climbing, but if I had to guess the story will center the main character going through a lot of personal growth while attempting to scale a mountain (a la Celeste, also a great game) and overcoming a lot of adversity to regain some self confidence.

Magical Diary is a fun little game about being a teenage girl that goes to wizard school. There's 2 but I only played one: https://store.steampowered.com/app/211340/Magical_Diary_Horse_Hall/

My time at Portia and my time at Sand Rock are pretty chill. They're kind of like Stardew but 3d, and I liked them more. It has some fighting but it's very PG cartoon-ish. It has a major mechanic where you just hang out with the NPCs, or go on dates with them. The second game, sand rock, is better but they're both good: https://store.steampowered.com/app/1084600/My_Time_at_Sandrock/

Sable, Supraland.

Melatonin is a sleepy rhythm game. Exact color scheme you're looking for, fun sleepy night time aesthetics. Not exactly in it for the plot

Transistor

While there are combat aspects of it, you can play the fuck out of Stardew valley without ever even seeing the cave. Definitely slice of life, with open relationship options(open as in mf, mm, ff, makes no difference. Not screwing everyone).

Coral island sounds right up your alley.

Try Minami Lane. It's a soft and cozy very light management game. Short and sweet. No romance or pink though.

No Place Like Home?

I don't know if you'd consider visual novels a game, but even if the 'character' you're playing is a male, the feminine aspects come out really well in Doki Doki Literature Club.
