New Jacket - Help Me

My wife is going to get me my first Barbour for Christmas. I am 6-4 and 225 pounds. Between the Ashby and Beaufort. Leaning toward the Beaufort.

First Question - what size should I get? I wear a 46L suit but would you recommend going 48 or 50 to allow some layers underneath?

Second - would you get the Beaufort in Sage or the Classic Beaufort in Olive? Trying to read about the differences but it seems the Classic is “softer” than the Beaufort. Is one better for colder weather than the other one? We’re going to be moving to New England in a city so likely will not be roughing up the jacket that much.
