My two cents doing some 2D stuff for a while (a cards game).
1. stick to SDL2 if you want to have something that will work in many places. SFML AFAIK is not so compatible.
From there, maybe I would start by mixing SDL2* libraries and using D with extern(C) interfaces if needed unless there is a well-maintained wrapper.
The rest of the alternatives just brought trouble to me when trying to run in many systems.
