You might be better off mixing and matching to get a triple Crankset.
9 speed shimano allows you to mix and match road/mtb and still has a range of replacement parts that can be sourced. But I wonder if 10 speed is a bit more future proof from a parts perspective?
Fwiw I did light touring using 10 speed shimano. Whatever the biggest cassette available was + compact + medium cage RD.
Not sure I'd recommend it as a permanent set up as the gear jumps and the huge chain don't feel as tight for normal road riding. However, as you need to prep kit for touring in any event, whipping off a cassette and changing a chain isn't that much work.
