If she loves organisation, “A Little to the Left” and “Unpacking” are cute.
Stardew Valley is being mentioned a lot and with good reason, there are a lot of elements to that game and you can choose which activities you like most - farming, mining, fighting monsters, foraging, interacting with villagers.
From there you can get a really good idea of what other games could be even better. For example if she loves the social side of Stardew Valley a Japanese Social Sim game might be fun too.
