I like blue with tans and creams, but as was said by the previous poster, the white would be too stark, you have all tans and creams. The second one looks like it could work, it looks like it has enough color to pull from for accent colors. It depends on what other colors you want in the room, but I do like the second one.

I like the suggestions of others, but if you'd rather keep things facing the window (prefer the view or would rather have a more open traffic pattern or whatever), you can totally make that work too. I think the picture window is a centered in the whole space, and you want your living space centered closer to the fireplace, so it may work better to have just one chair or unmatched chairs, so you're not trying to create a symmetrical arrangement in an assymetrical space. Also, it looks like you have a reasonable sized space where the keyboard (?) is. I would consider treating that as a separate little nook (not really connected to the living room) maybe with a cozy chair and side table, or a small desk or the keyboard, or whatever is useful to you.

I wouldn't do that fireplace surround. It's jus not a good look w/the type room/decor you have. try it elsewhere. try craigslist and similar sources for rugs, tables, shelving. as for the room layout, for the wall that's next to the doorway, and to the right of window (pic #3 up top) what if you did some cool shelving or book cases? I'd also look into doing some sort of shade or blind instead of those bulky drapes. This is a simple layout you could copy. a larger sofa w/a chaise would work for that room better than your two sofas. if doing a tv, try a shallow console and mount the tv to the wall. you can do a 'coffee table' by utilizing an ottoman or something similar. this type of sofa against the large windows would work out better. notice the blinds, nice contrasting paint color on the walls, colorful rug, potted plants. same layout. Imagine your windows are behind the sofa. shallow shorter shelving on the opposing wall is great for kids toys and books. mount tv. fabric ottoman for coffee table. neutral rug.

One idea might be to add a very short wall on the left as you enter the living room so the opening to the living room is the same width as the entry ... and, by doing that you could put wall to wall built ins on that end of the living area, with or without a tv, and still create two separate sitting areas. I don't understand the "bar" against the solid wall behind the pantry and refrigerator. If you changed the pantry to a "butler's pantry" with a pass thru window, that would have made more sense. Is your "bar" a cabinet something built in? Have you considered either closing or narrowing the door between dining and living room and/or creating your pass thru bar there with your piano in the adjoining corner adjacent to the fireplace near the dining room wall? https://www.decorpad.com/search/butler-pantry-pass-through
