Let go of the idea that you have to have the sofa or any furniture at all against a wall. The best solution is to "float" the sofa, in your case, to face the fireplace. Get a really nice very large rug, put it in the middle of the room to anchor the space, and place the sofa and coffee table on it. Some shelving to the sides of the fireplace would be an ideal place to place a TV--on the right unless you have a huge TV. A nice easy chair on the left of the fireplace under the window with a floor lamp or shelf lamp behind it would make a cozy reading corner yet would add to your conversational grouping. Do a Google search on "floating a sofa"

This is a crude drawing but goes with what I described below. Floating furniture and making two seating areas will eliminate the waiting room feeling. You'll need more pieces. Here yellow is seating and blue is casegoods (more or less) plus lamps, plants. "X" is just not in that location. Added TV to the big wall end of the space. The description starts at the top of this illustration and works through to the bottom of it. Hope it is helpful and you have some budget for added items. Angle your two chairs flanking the console. Hang art 5" above the console and keep it within 75% of the console's width. Add 1-2 lamps to the console. Then turn the loveseat to face the console and two chairs. Put the coffee table with that group (12-18" from all the seats) and you have one sitting area Push the larger sofa up behind the loveseat to face the big empty wall at the other end. Back to the console side of this, fill in the area where the big sofa overlaps the smaller one with a pair of plants that do well in low light like ferns or palms in nice baskets for some texture. Buy two more matched small coffee tables, a backless sofa, and another pair of swivel chairs. Float the backless sofa with the two small coffee tables either side of it. Add the swivel chairs on the side of this group nearest the large wall. The two small coffee tables serve all 5 seats so allow 12-18" between each seat and the tables. Buy a credenza and TV for the big wall. Flank it with two large scale floor lamps. Hang a gallery wall opposite the window. Here is a backless sofa. The two smaller coffee tables would be on either side of it, all three between the larger sofa and two new swivel chairs.

I don't believe that's enough light. You need ambient, task and accent lighting, and you only have two of the three, and they sound/look to be inadequate. Paint is the last item chosen in a decor scheme. It must work with the fabrics and textiles which are set in stone. Paint color can be custom blended to work with those. Since your sofas are neutral, what other colors will you use in your space? Once you narrow down your choices, order big peel and stick samples from samplize.com so you can move them around to all walls, in all light/weather conditions to be sure of what you'll see once you've painted.

ugh, Houzz failed to post my comment from before. I recommend large, tall open shelving, but sparsely decorated so it doesn't seem too cluttered. you can DIY this by buying 3-4 ladder shelves. they could be pushed together or spaced a few inches apart. there are kinds that lean, and kinds that are straight. get really tall ones for your space-- which you'll need to bolt at the top so they don't tip over. if you didn't want to bolt into brick, there are kinds that anchor to the ceiling and floor. I believe some types don't bolt to the floor, but grip it instead. these kinds of bookcases can get pretty expensive -- you have to contact special places that will supply you with tall enough poles. not usually something you can just get off of wayfair. but they are really stunning! https://www.archiproducts.com/en/products/bookcases/floor-ceiling-mounted
