So the block in the middle of the floor is the couch plus table? I see faint pencil marks but can't make them out. If that is the furniture outline, you won't have much room for anything else. Can you explain these dimensions? The width is something you might find for the length of a conventional couch.

The block in the middle is the footprint for the couch (160.8” x 87.5”). Since the wall juts out in the corner, I assumed the footprint should also be adjusted.

I assumed 30” setbacks on all sides except for the stairs where I assumed a 36” setback is required since it’s a heavy traffic location.

I assumed the footprint of the console table to be 13” x 160.8”, located behind the couch. This is the narrow rectangle I drew.

IMO the couch is way too big for the space but honestly I have no idea what this couch would even look like it is the size of 2 big beds . 30" wa;lkways are not good and furniture crammed in a space is never a good look. Post a pic here of the couch please .Post here in a comment DO NOT start another post.

This is the couch my partner was looking at.

What width of walkway do you recommend then?

If you want to test drive the fit/flow of the proposed couch/console, consider putting some cardboard boxes around on the floor that match the actual perimeter size of the couch and see how you feel after a couple of days navigating around the proposed couch.

That "extra deep" version is just huge - even in the picture with nothing in it for scale! it will fill your room physically and visually. Do you have a large number of people you need to accommodate all at once? Or will it be a playground of sorts? I'd consider function and form here - how you will use the couch, because there won't be much room left over.

It would be the sofa that ate the room. I think 36" is the minimum amount of space you want for traffic patterns, and if that is the clearance on all sides it's not enough. This is more appropriate for a basement rec room/TV room. If you don't have a basement in this home then maybe the next one. :-)
