Luna, no bench? You need to do the actual movement to get better at it (that is your goal right?).
Incline press really doesn't have much carry over to flat.
Floor press/1 board press can be good for overloading the CNS and getting you used to heavier weights, but you still need regular flat bench in there to get better at the movement. Bands/chains/boards...they all strengthen the mid->top portion of the movement. You may get strong on these, but when you switch back to regular bench to test it, you are going to be weak out of the bottom, which is where a raw lifter needs the most focus.
If I were rotating 3 lifts, I would do close(r) grip bench, followed by a variation that adds overload (bench with chains, 1 board, pin press, floor press), followed by your regular bench press.
Just trying to help you out because I don't want to see you waste your time.
