I highly recommend against a powder blue. This is not an ethical home for a fish that swims several miles per day in the wild at times. They're very active and stress in confined tanks, particularly those less than 6 feet long. The minimum size is 180, and I would argue even that's small for a full-sized adult.
Good suggestions: Tomini, Kole, Yellow, Perhaps a Purple. As far as foxface go, they're not as active and most varieties will do fine in a 4 foot tank.
Since I made the first post I have completely ruled out PBTs and any larger tang. I am mostly looking at the Yellow Eye Kole right now. I am not sure if I would do a Yellow Tang in a 120 so I might go with a One Spot Foxface instead.
