Ceiling, Alabaster in flat finish, trim, Alabaster in semi-gloss finish. Because the cabinets are abutting the ceiling and Alabaster isn’t true white, I would worry that a ceiling “white” would make the cabs look drab.

I suspect the paneling above that appears to be on an angle, is a bulk head for something, and I would be very cautious, trying to remove it. It may hold plumbing pipes, or it may hold ac vent pipes, etc. I would paint the walls all to match, but, leave the wood on the slanted ceiling part. I would paint the bookcases white too (different sheen, but, same color white as the walls), but leave the mantle like it is.

I like the decor and colors they used to stage your chair. I like the blues, whites, and grays. Use those colors throughout, they look good with the wood tones and your kitchen -- and extend the blue paint into your kitchen. Those sconces are placed as if an exterior treatment. Remove them.
