stardew valley is up there as one of my favorites!!! there is also harvest moon, though ive never tried it
I can definitely also recommend SDV! There are some problems with HM, though - basically, the name originally was used for Marvelous' Bokujou Monogatari series, but when they started localizing the games through their subsidiary XSEED, they changed the name to Story of Seasons, while Natsume, who originally localized the games in NA, kept the name Harvest Moon and now uses it for their own games. While One World looks interesting, I don't think any of the previous "Natsume Moon" games were very well-received, and honestly, I wouldn't recommend the SoS games currently available on the Switch, either. Maybe keep an eye out for SoS: Pioneers of Olive Town when it comes out, though.
On that note, the Rune Factory series is also similar, if you like those games - it's basically farming with fantasy elements, so you also go out and fight monsters, explore dungeons, etc. RF4 was super popular and got a deluxe port for the Switch with some added content, and RF5 should be coming out in 2021.
