I recently added my $0.02 to this thread, but happy to post a pic here, as well:
My workbench is an old Costco 24x96 wood-topped “workbench” that is a wooden top on a metal base. Its top is 38" high, so I sit on a stool to work. I built the spray booth that takes up the left side, and I’m currently using some drawer pedestals from my old work desk (currently re-purposed for a gaming computer and flight simulator setup), but I really want a better drawer option. These ones don’t really fit anything useful for storage, or at least I haven’t found anything yet.
The stash is actually the bottom two shelves in a wall-mounted lumber storage rack (note the lumber on the top shelf). When we moved here, I was setting up my woodworking shop in the basement, eventually the space became more of a “maker space” to give the kids places to experiment and do things. Also, the sag in the bottom shelf is not from the stash! It (the shelf) spent years holding smaller lumber pieces that were shorter than the space between supports, so it’s actually had a significant amount of weight on it in the past. I just like that it makes it look like I have SOOOO MANY MODELS. 
Finally, the clear racks on the walls are ‘spice racks’ that I installed early on. I will likely remove some or all of them as I am outgrowing my current storage and wish to add more paint racks and desktop drawers. If I can find a way to reuse them, I definitely will (see “primer” shelf in paint booth). Current thinking is mounted on the wall left of the booth, so I can store rattle cans and larger containers out of the way.
I love some of the spaces I’ve seen in this and other threads - I cannot imagine a time where I will ever have my own “model space” that holds display cases, etc. but I can dream! Keep those pics coming…
