Perhaps some Woven Wood shades like these would look nice with your floors and fireplace?

Is the room wide enough to turn the sofa to face the fireplace?

No the sofa is too wide to turn to face the fireplace.

Why are there 2 coffee tables at all. You need a small table between the chairs some lamps for lighting for sure and a narrow long coffee thable if there is room a rug with some color and art for sure. What do you need in the way of window coverings if privacy then go with drapes IMO not blinds and for sure not wood ones. If you want a ceiling fixture it needs to be bigger and closer to the ceiling.

What a great space to work with! Here's some inspiration for you:

Switch sofa to window side. Hang heavier fabric window panels all the way from floor to ceiling. Add top down bottom up blinds with window panels. If there is space in the corner on right side of window I'd place an arched floor lamp. Switch chairs over to solid wall with a low round end table between them & a tall table lamp with good sized pieces of art above each chair. I'd hang long wall sconces on each side of the fireplace with cabinets underneath with accessories. Add a large light fixture that ties in with wall sconces and drop it down to align with the top of the flat screen & window trim. 8' x 10' area rug and a narrow coffee table with drawers. Drama created with pops of favorite color in rich jewel tones. If your not in love with the stone I'd paint it out same as the wall.

I'm thinking a light rug will boost the appearance of the room. Add some wall decor on either side of the fireplace. Leave the sofa on the big wall. It will require a large piece of decor above and it's easier to accomplish that with the sofa than with two chairs.

My concern is the high TV and position of seating, which forces viewers to turn sideways to watch TV. Have you tried sofa on window wall and the 2 chairs positioned facing the TV?

Wow! Thank you so much for the effort I didn’t even think of doing that! love the details. Can navy blue be integrated in there? Or is brown the way to go?

Great ideas for color, etc. I would add that a kidney shaped coffee table (or any oval creative shapes) would add a
Lot more personality to a very linear space. The very dimensions here limit the layout somewhat, but breaking up all those lines with a curved accent piece would be a welcome addition.

Wood medium tone coffee table would look good

I have to leave now, I will probably do better with navy later.
