This is just telling you which of SRAM's pregonfigured chainring options on their complete cranksets it can shift.
Ah, that makes a bit more sense. Still not much wiser whether I'd want a low or high clamp and if it's going to reach, though :(
Road cranks with mtb FD?
Yes. I'd go for a 1x but it's 130bcd and all the narrow/wide chainrings in that bcd look ridiculous. I'm considering sticking a chain catcher on instead.

The chainrings are further inboard on a road crank than a mtb one. I don't think you'll get a MTB FD set up correctly to work with road cranks

Low clamp generally used for mtbs with the ST bottle bosses lowered so it doesn’t foul them.
Praxis do a nice looking 130bcd NW in 40 and 42t. The old model with different tooth profile (think they got told off for copying someone elses) could be had cheap last time I looked.

If it can shift 22/36 which is a 14 tooth difference then it can shift the 10 tooth difference of your 38/48 no problem, providing you can mount it in the correct place in relation to the larger chainring (regular FD setup).
Some manufacturers adjust the curvature of the FD plate to ensure better shifting with smaller rings but in reality this makes little difference.
