As far as rear fork ends go on a commuter, my preference (in order) would probably be 1. sliding vertical, 2. horizontal, 3. vertical, 4. track ends (only under duress as they make it more difficult to change a tire with fenders).
Most of us buy a frame/bike for a specific purpose, and stick to it. Vertical dropouts are the best option for derailleurs, AND for disc brakes. If I wanted an IGH/fixed/rohloff frame, I'd buy one - all all three of those would be different. The horizontal dropouts are the only complaint I have about my casseroll. They're unnecessary, and a hassle for my purposes.
BTW, horizontal dropouts also make removing a wheel more difficult with fenders mounted.
