If you want to use the floor-standers, it looks like your option is to put one on top of the fireplace ledge, and fish a speaker wire under the carpet to the other side of the doorway for the right speaker. You’d have to put the right speaker on top of something to make their heights match. Not an optimal layout, but better than soundbars or in-walls.
When we were home shopping ten years ago, practically #1 on our priority list was the living room had to be “home theater friendly,” allowing for symmetrical speaker placement for fronts as well as surrounds, a good corner for the subs, and attic access for cable running.
