So you're looking for just a stereo pair for that rather sizable room? I think any of the speakers you have listed will be eaten alive trying to fill that space, as may your amps.
Just off the cuff, I would probably use the far right wall, and get something with high sensitivity, somewhat narrow directivity, and that tends to project the sound. Cost no object, I would think a pair of Danley SH50s and a couple or more subs would do the trick in that room, and do it splendidly well, but that's no small-coin setup. You're going to need some seriously big and sensitive speakers to fill that space.
