Couches are not "a focal point" in a room. Focal points are typically architectural things like windows, fireplaces, or can be a large piece of artwork or a unique lighting fixture. And those couches specifically should not be highlighted in any way. Couches also need to be pulled into the center of the space, they should not be pushed up against walls in an L configuration. And gray is not a "bold" color. So now that we have that cleared up ..... the first thing you need to do to determine furniture configuration in a family room is to decide where the TV is going, and then situate the furniture around that. And oddly enough there is usually only one place a TV can go in a room, so it's usually not much of a decision. From what I can see, it looks like the wall it is currently on is where is has to be. So then pull your couch into the center of the room to face it. You will need to get rid of the love seat, there is not enough room in that space for it. Then get two accent chairs to complete the seating arrangement. I wouldn't put anything on the "odd" angled wall next to the TV because it will just draw your eye to look at and it will just distract from the TV. Just leave that wall blank as is so that it just "blends" away. Then get a larger console to go under the TV, the one you have now is too small. Remove the mirror on the wall. Remove the drapery panels and replace with blinds.

Size, square footage is difficult to get a feel for. I agree with the color comments but think your drapes add needed movement and design to all the flat color,you could go bolder more like the pillow in the dk blue and gold. Shades just make a room look empty and not quite finished IMHO. Move the couch forward. Maybe angle it a tish see what you have room for in the way of side tables. The challenge will be not leaving a welcoming walk way into the space. Your plant is large enough to sit on the floor. If you could find a real statement piece in the way of a console that would add needed dimension and interest. What you have is just too small. It should be larger than the TV for a good balance. Seeing the room from other angles would help a lot.

Can you stand in the corner of the room to the right of the mirror and take a photo of the room from there?

As currently shown, I would want the TV on the next wall over to the left in your photo and add an armchair on the wall that currently has the TV. I agree that the console under the TV is proportionately too small.

I find the blue-gray of the couches with the warm colors of the floor and walls unsettling.

Post an actual scale drawn floor plan. But honestly I have no idea what you want since I see no bold color anywhere I do see drapes that always say to me I couldn’t find enough of one kind. You need a much wider TV stand and you can lower that TV . Get some art , lose the mirror and then come back.

This is a personal preference to me: gray (cool neutral) does not go with beige, tan or brown (warm neutral). You’ve got all kinds of neutrals battling here, but no color.
