If you choose between X-T1, X-Pro1, and X100T I would go with X-T1. The newer bodies have much better AF. Also that has the best EVF. If faster AF isn't important then either the other two would be fine.
I have the X-E2s, a very good deal now, and the X-E3.... both highly recommended. The F2 primes at 18, 23, 35, and 50 all make great kits with these bodies, but the kit zoom 18-55 is a gem for a kit zoom and a one lens kit.
I shoot with µ4/3 and Sony a7 too but Fuji is my favorite. The lack of an AA filter makes for very sharp and detailed images. Sony a7 is my favorite for use with rangefinder and legacy lenses.
