I used to display my whole collection at once, but now I rotate displays. I throw away boxes because they take up too much space and I'm selective about what I buy, so I don't care about the resale value (I've only sold a few figures in several years, mostly ones that turned out worse than anyone expected or ones that got updated in reissues).
I use two of the uline containers from the OP for accessories, and I print little tags to stick on the front of each compartment so I can quickly find a character's accessories.
For storing figures, I put them in archival quality bags and store them inside stackable stemware containers. The cardboard dividers are the perfect size to store around three 1/12 figures each, or one larger character.
All of this fits into a very small closet where I keep all collection-related stuff. I rotate displays into new scenes/dioramas whenever I get tired of the old setups or when I get new figures.
If I don't display something for a long time (around a year), I consider selling it. That doesn't happen too often, but it happens.
