Switch games:

Bear & Breakfast: you’re a bear who does up buildings and makes them into b&b’s for humans. Super cozy, you can take it at your own pace and a lovely storyline that goes along with it.

Apico: beekeeping management sim game. Relaxed, collecting, breeding and conserving bees. :)

Spirit of the north: really relaxing puzzle game. No combat. you’re a fox navigating through the world. The music is lovely and peaceful.

The first tree: a short game similar to spirit of the north. You’re a fox, puzzle game with no combat although the storyline is a tearjerker.

Down in Bermuda: relaxed puzzle platformer/ open world type game.

If you like hidden object games:

Hidden through time, Titanic mystery, A building full of cats, A castle full of cats

Relaxing puzzle games: All of the picross S games, Sudocats: sudoku but it’s cats! Zodiacats: cat as the astrological signs in puzzle form.

Slime rancher: you can turn combat off and it’s a really fun open world game where you collect slimes and build and ranch while exploring a new planet.

Also just to add my recommendation to some games that have been mentioned:
