First, put up a new building that the city insists must be smaller than you wish and covered in whatever your house is; in this case, metal covered in sandstone.
Closet Maid from Lowes is what I use. The white finish does not stand out against a white wall, and the parts come in various sizes and lengths. Here they are mounted with 2 inch 5/16 self tapping exterior screws. It might be more expensive, but only once, and if you count 5 empty slots between shelf brackets, well, that's an AD's height. Plenty strong if the mounting foundation is good.
I do have some John Sterling, but they visually stand out and are not as finished. I use those for containers and such. First, the brackets are taller, and second, the bottom of the brackets are where the ends of the stamped out metal is ... in other words, lift a 40 pound lightbar up into place, go to high, and scratch the dome on the shelf bracket above.
A floating bookshelf works, too. Metal; small magnet mount beacons stick (too) well to it. It has a base, but I imagine it could also be mounted to a wall.
Other things:
Bulk candy racks with custom aluminum shelves and/or Grainger shelves for some other product of theirs.
VHS Tape cabinet ... 8 drawers of about 5 inches deep make for great parts and lens storage.
Old hardware store displays from DeWalt. They roll around, too, carefully, like the other things above.
This building is fairly sealed up, but I can still move everything easily to clean, so think wheels or felt pads for things on the floor.
