I don't know what your application is but for most bodies the projected area is used for calculations. Pressure coefficient, pressure drag, skin friction, viscous coefficient will all be calculated according to the exposed external surface.
For your question if you need to compare two different datas, you can use Cd and Cl. Cd and Cl will be calculated according to the reference area.If not you can use the forces on exposed areas but i don't really know what your case is.
