Since you said you're a Nintendo gamer get Rare Replay.
The Xbox Series S has access to various Xbox and Xbox 360 titles. So if you haven't played these titles I'll recommend Metal Gear Rising, Sonic Adventure 1+2, Sonic Unleashed, Sonic Generations, Panzer Dragoon Orta, Castlevania Symphony of the Night, and some more. I also hope they add more titles.
As for Xbox One titles there's a lot, but I start by saying Resident Evil 2, Bayonetta (also can play Xbox 360 version), Vanquish (also can play Xbox 360 version), Monster Hunter World, Dragon Quest 11 S, Octopath Traveler, Nier Automatta, DOOM, DOOM Eternal, and more.
