You gotta start with the Final Fantasy games if you haven't played them yet. The best ones are 4, 6, 7, 9, 10 and 12. These games kind of set the standard that all other JRPGs are based on.
After the Final Fantasy games, I'd say Octopath Traveler and Dragon Quest 11 are good Switch games to try out. The Dark Souls games have a very different vibe, but are also extremely excellent JRPGs. There is also Final Fantasy 14, which is an MMO, but it is redonkulously popular right now.
