I vote for hardwood or engineered wood through the whole space, including the kitchen. Opening the wall would be nice, but I suspect your appliances are arrayed along that wall? I'd paint the wall the same pale color as the living space, and hang a really big mirror on the wall if you can't open it. Then you open the wall visually, and reflect the light from the sliders back into the space. (I know...me and mirrors. They are great manipulators of space, particularly when you commit to making them big!)

I think the colors currently on the walls work fine. I might suggest however that you remove all the small understated wall and sparsely spaced pieces replacing larger more intentional ones for impact. If you opt to keep the art and pictures on the walls they need to come down to eye level height. Rather than painting entire walls you could paint the transitional walls like a bridge (the one by the stairs and the one by the front door). You could go with a latte, coral, grey, or gold. Good luck.

Have you considered a pretty white? That would probably look better with beige furniture. BM Swiss Coffee, White Dove and Chantilly Lace are all nice possibilities.
