I'm setting up my new CX bike 1x10. Before going 1xN, make sure to think about how you want to use the bike. 1xN works well for CX racing because you generally don't need a huge gear range. Really low "granny gear" stuff you just hop off and run. Fast straights are few, and usually short enough only the pros can take advantage of big gear inch ratios. So an 11-28T with a 38 to 44T chainring (depending on your strength and typical course) and you're set. It turns out that this setup is also not bad for road use in non-mountainous areas.

MTB 1xN setups will use a wider range cassette and a smaller chainring. This means bigger jumps between gears and a lower top-end, but that's not a huge concern when mountain biking. On the road, big jumps between gears can be really frustrating. And your 38-11 combo is going to need a 110 cadence to hit 30 MPH. Maybe not a big deal for commuting; could be more of a concern for training or group rides. No harm giving it a try, but understand the compromises.
