I am 6'2" but don't own a Fuji. I ride frames from 58-60cm, I wouldn't go any larger or smaller. Don't worry too much about the stem length, it can be changed. You have a bike now ? and it's comfortable ? Measure the saddle nose offset from the BB centre, measure the handlebar distance from the saddle nose. Keep these distances the same on the new bike. NB on two of my bikes I have 130mm stems.
