I use a plastic tool box for everything... I label the toolbox with whatever is inside and I built shelves that are just the right size (height and depth) for the toolboxes. For the shelves, I used those 90deg metal shelving brackets and 3/4" plywood that I ripped to size and then routered a nice 1/4 circle edge on.
For example: (toolboxes)
I have a hammer drill with the all of the hole saws in one.
All of the boat maintenance items in another (oil sump pump, orings, outdrive pump, etc)
Worm drive circular saw with all of the blades in another.
Auto electrical stuff in another (solder gun, connectors, wires, crimp tool, strip tool, wire loom, etc... )
All of the plastic toolboxes that came with tools (drills, saws, etc)
On and on...
For the bigger items, I use the 16 gallon tubs and label them and have built shelves that fit these perfectly.
In our 3 car garage... I am able to park the truck, the Durango, the boat and all of its stuff (skis, tubes, props, cover, kneeboard), 6 bikes, two very large roll-around toolboxes, Xmas decorations, all of my family's shoes, all of my wife's teacher stuff and all of my "stuff"... Its very full and 98% organized...
I keep all of the yard stuff (lawnmower, edger, chainsaw, pressure washer, wheel barrel, saws and shears in the yard shed (6' x 8').
