Without knowing what kind of games you like, I can safely suggest Splendor and Azul. Both plays well with 2 and scales up to 4 equally well. If you like more strategy, Lords of Waterdeep.
There are some excellent 2 player games as well. I would start with Patchwork. If you like something more heavy, 7 Wonders duel is an excellent game.
