I was thinking of doing a build with 1x drivetrain but if I'm looking at the possibility of going with 36T crankset with 11-36T. But does this present a problem? I mean there are manufacturers going for 38T and 11-34T. So would choosing a cassette that goes up to 36T cause any clearance issues?

So would you go...
36T and 11-36T
36T and 11-34T
40T and 11-36T
40T and 11-34T
