You can hide wires, or probably snake cables through to get them where you want them, or get wireless system in total. If I am reading the drawing correctly, this room is only 11'-5" wide? So, I don't think that is sufficient space for putting walkway behind the sofa. Sofas are typically at least 36" deep and consoles are 16-18" deep. You need at least 7' from TV for viewing probably further is better depending on size of TV and you need 3' for a walkway. 3+3+4+1.5, means tight. I would put the TV on the opposite wall. You will have some traffic, but I wouldn't let that be my limiting factor. The lines of sight to the TV would be much better with the TV on the opposite wall. So, think about it. You could put boxes up in the configurations (i.e. simulate sofa and tv console in each configuration) and see how it feels from a volume and traffic point of view. I would definitely go for TV on the opposite wall. More room for coffee table and a couple of extra chairs. That might help you decide.

IMO a sectional in your space is the wrong choice. I actually love the sofa and the 2 chairs you have in that space. Setionals are IMO the most expensive way to get the most uncomfortable seats. Arm rests = comfort and a sectional at best has 2 no matter how many seats . So everyone else is sitting just like they do on the middle seat on a sofa the seat no one wants.

congratulations! I would remove the mantle and hang the TV above the fireplace. Center a large area rug on TV/Fireplace. a credenza under that pass through, sofa moved much further forward. I would think of the Right side coming out of the kitchen as the dining space... as it is on the way to the patio. Get the largest table you can fit there, if you need for 4 go with 6. All good wishes on you new adventure!

I understand why you wanted to have the bistro table/chairs on the window wall between the patio door and the kitchen passageway….it makes sense to have your dining area adjacent to the kitchen. The open wall at the opposite end is the perfect location for the tv. So swap the sofa and loveseat and anchor them and the cocktail table on the rug (front legs of sofa/loveseat on the rug), so the loveseat will pull in closer to the fireplace, leaving room behind for the dining area and access to the patio door. The square end table could then be placed in the corner between the sofa/loveseat.
