Yo!
I'm going to build Santa Cruz Bronson v3 this spring, I decide to get 1x11
XG-1150 casette (10-12-14-16-18-21-24-28-32-36-42T)

But I don't know which chainring and cranks choose: 30 or 32t, 170mm or 175mm?
Any Ideas?

Knowing a little more about the type of riding you'll be doing may help people provide better insight. Is climbing or speed more important to you? You'll have an easier time climbing with the 30T but you'll lose top end speed.

Based on where I ride, I would use the 30T with that cassette. My rides are typically between 10 and 25 miles with 1500 to 3500 feet of climbing. Crank length wouldn't make much difference to me. It may have more of an impact on bike fit and biomechanics than performance gains.

My ride is almost the same, 20-50km , 300-1000m climbing.
Size L, I am 1.8m so i have preety long legs.
I would like to make this bike max universal as it possible. 100% enduro with some jumps, but next day just ride with my girl outside the city Wink

I would say 30 / 175 should fit your profile and program.
