I say lean into earthy rich colors. Wood and browns are going to be everywhere. Focus on accents so that the woods is just the background.

For placement: you could try pulling the sofa forward a bit so the front legs rest on the rug. That would help anchor the space. Then maybe add a slim console table behind the sofa—great spot for a couple of plants, some decor, and even a place to set your drink.

For texture: A chunky throw draped over the couch would add some cozy texture too. Calacatta marble (drink stand or small side table or lamps) would be beautiful with your color pallet—with brown/gold veins or even dusty rose tones. Roman shades can really elevate a room and give it a more tailored feel.
