Try wood and glass. Consider hanging the mirror vertically and about 5" from the sideboard top. You could also move the table under the light fixture, change it out for a chandelier, and put the sideboard and mirror on the clock wall where the mirror could double the chandy which should hang 36" or less above the table top.

I like your plan but I don't think a pattern on the bed wall is a good idea. The carpet already has a lot of pattern so I'd keep that wall a solid, dark color, from the rug. Add some sparkle like mercury lamps for the bedside tables for interest.

We had the same issue in an old kitchen, we went with Coopers, There is a stripper then wax that will soak in. The stripper is in spray bottles, but I'd send the dogs on holiday or keep them outside while you're doing it. It'll take some elbow wax, but will look amazing when you're finished. Good luck!

The all black kitchen looks scary as. Maybe because there's no lightness in there at all.
