What are the most common screen resolutions to have in my options menu

Surely the resolutions depend a lot on how fast your game is. An i$$anonymous$$ac can have a 5120x2880 screen. Does your game run okay on a display this size? Some monitors can have a 2560 width and 1440 screen, so that might be "large". I'd suggest getting the game running on some of your friends machines and check that the resolutions they use let the game run okay.
