I have a very similar room my wife’s 12x12 sunroom with windows on 3 sides a tile floor and cathedral ceiling. Also limited options for placement within. It’s an acoustic nightmare. Lucky it’s not my main listening room.
Having tried many speakers in there larger and smaller over the years in this case smaller was best. Currently using tiny Vanatoo Transparent One Encore actives in there (angled up slightly on short isolation stands) and am happiest I have been with the sound in there.
Smaller may be best in very lively rooms

Also have used these 8” Ohm Walsh speakers there to good effect but was overkill for me in there:
