Looking for a closed stylish surface-mounted box for the bedroom

Depending on how far the painting work has progressed, another option would be to install a flush-mounted box, put cables inside, and place a blank cover on it. This would be significantly more compact than the surface-mounted frame. Alternatively, some function (recessed wall light/baby night light or orientation light/power outlet etc.) instead of the blank cover.

Of course, the painting work is already completed. I think I will use a flat canopy for the lamps and take the wiring from the power supply.

Freely following the motto "Not pretty, but rare"

For something to go in front of it (pictures, TV, speakers, etc.) it’s probably too deep, right?
