With ambient light the FH will be a better choice as well as going slightly smaller like the 100". It does have a reduced viewing angle but the question is do you have off angle seating/ viewing areas? It is not a concern if the couch shown is the main viewing area. Hot spotting can be reduced with good projector placement and I doubt would be an issue if the PJ is going to near that back wall, the shorter the throw the more hot spotting would be a problem. I'd move the projector as far back as possible and avoid horizontal lens shift with a gain screen by keeping the lens centered on the screen.
