Here's a rough shot of my tool organization. It's an older pictures, it's been updated a bit since. There are several tool chests for screwdrivers, pliers, gooey stuff in tubes and the like, but anything I use on a regular basis lives on The Peg Wall.
Each of those two tool rolls is for wrenches, one SAE and one metric. The sizes of each is written on the roll, means I can grab a 14mm instantly without scrubbing around in a drawer. Tool rolls travel well, too. There are some other wrenches in little racks on the wall. The sockets are hanging below and a bit to the left of the rolls with the ratchets beside them. You can also see the big torque wrench, clamps, a rivet tool, rivnut setter, electrical crimping/stripping tools, tin snips, tire gauges, hammers, several sizes of pliers, vice grips, the common screwdrivers, t reamer, etc. Tapes are hung just off camera along with a bunch of Sharpies.
There's more pegboard on a wall at right angles to this one, it mostly holds drills, angle grinder, electric impact gun, measuring tools and - most important - ear and eye protection. It's not every tool, but it covers 90% of jobs
Here are the socket rails I use.
