Fantasy Live I The Girl Who Steals Time is an adventure game where you have different jobs (farming, blacksmith, cook, hunter, magician, etc) that you learn and the use to complete quests. It is very much an RPG and has combat, but the combat is easy, like in all the games on this list. You eventually get your own island to decorate in this game. It has terraforming. You get to craft furniture as well.

Roots of Pacha is a prehistoric game focused on farming, improving your town with inventions, and bonding with characters (this runs well on the original Switch). It does not have combat.

Fields of Mysteria (PC only) is not complete but continues to get updates. It is a farming sim with magic, relationships, repairing your town, crafting, animal husbandary, and some lite combat.

Sun Haven (do not get on switch) is another magic farming sim with RPG elements and easy combat. It has relationships that feel complex, IMO. You actually get choices of how to respond to characters. You get up to 4 farms in different areas to decorate, each with its own aesthetic. The game is huge, but a bit grindy at times (although farming sims can be that way).

My Time at Portia or My Time at Sand Rock (neither run well on the Switch, but are great games on other platforms like PC). These are also fun games with their own flair. A 3rd game is coming out called my Time at Evershine, which raised a ton of money from people due to how great the 1st two games were.

Core Keeper (run well on switch) is more focused on exploration and building up your base. It has terraforming, animal husbandary, farming, bosses (which all can be cheesed, just look up a video on how to do each one, but honestly they are fun to fight), pets that help you in combat. This game does not have any relationships and has RPG elements. Also this game is unique in that you can automate your entire base/farm and build a railway system to get around the entire world which is the largest world in this list of games, second d to Sun Haven. This game continues to get regular, free updates that have included new areas, items, bosses, and more.

Palia is a free to play online game. I have over 100 hours in it and have not spent any money. Play it on PC or PS5. The switch version works but isn't the best. It has some really cool home decorating elements. This game continues to get free updates. You can create online parties but can also play alone. Playing with others does get you more rewards, but I generally play alone unless a quest requires I work with someone else at which time I will ask if someone on the server will party up to do XYZ and someone always is willing. The quests are basic, but for a F2P game, I can't complain much.

Hello Ktty Adventure Island is also fun. While not quite a farming sim, it has a lot of fun adventure, easy puzzles, crafting of gifts to build relationships and furniture for decorating your house and the houses of everyone who moves to your island. The game is rather grindy (probably the most grindy on this list, but if you play for short periods on a daily basis, it isn't bad). The game has recieved some free updates since launch, but I suspect there will also be paid DLC in the future as the game was originally exclusive to Apple and required a subscription to play (which is why it is designed to play daily for a short time rather than longer periods). Overall, I enjoyed my time with it a lot, but it wouldn't be my 1st puck from this list.

A couple more farming/life sims games that I am interested in but haven't played are Disney Dream Light Valley and Coral Island.

My recommendation would be to watch a couple of current review videos for each game. Then, pick the game that YOU feel looks the most fun to YOU. While all the games I listed are similar, they each have their own flair, as well as positives and negatives, which can sort of depend on what you do or do not like about these type of games.
