I have "Plano" semi-clear plastic trays for hardware, electrical, fitting, auto hardware, etc. About 3 dozen of them. Mostly organized by type of what's in there (screw anchors, plumbing washers, brake hardware, to name a few examples). These are my small parts and are grab and go.
I have a few of the "Yellow and Black" larger trays for bigger stuff. About one half dozen. For sprinkler parts, lock sets, electrical devices. The bigger stuff that needs to stay together but they are more storage-type versus project-type storage.
I have the "arko" bins above a couple of my benches, about 32 lineal feet in different sizes. I simply don't have enough hardware and fittings to have a need for a big wall of these (although I would love to some day). These have either the stuff I need at hand (sharpies, razor blades, garden hose fittings) or stuff I forget I have that I keep buying. It's not great storage for non-used stuff but keeps it in front of my eyes. I actually use the bigger ones for Raco boxes, covers and Romex fittings because i keep buying what I already have. Your results may vary.
I have a bunch of blue Swiffer refill trays for the stuff I want to store, the stuff the OP was speaking about. They are free, of course. They fit on shelves in my gladiator cabinets. I have one of power bricks, one for garage door parts, one for pulleys & clevises, about 3 dozen in total. I label these. They are not as elegant as the Sterlite and shoe box style bins, but they show up about every third time I month floors.
As for the hoarder comments, I "get it". But I keep a lot of little stuff that I can't be bothered to run out for. At my cabin, it's a 2 hour round trip drive to town, and stores aren't open after 5 PM. If you need something after about 3:30, you are done for the day and will kill most of the next morning going to get it. For a plumbing or electrical part that's a few bucks, it's better to have it in stock than be without utilities for close to 24 hours. (The hardware store actually delivers weekly, which helps a bunch.) Even at home in the city, it's an hour round trip to the box store or the Ace, worse during traffic hours. So I keep stuff.
