On this general topic, I'll mention the Milwaukee Packout system. I've been converting most of my storage containers and portable items to Packout. https://www.milwaukeetool.com/Products/Storage-Solutions/PAC... https://www.pelicanzero.com/packout-nation/
I prefer the Tanos Systainer stacking boxes. They're small enough that each box can have a single purpose. For example, I have a drill, impact driver, charger, spare battery, and all of my drill bits inside one medium box (very heavy). In an XL box I have a track saw with its accessories, in a small box I have a jig saw, and in a medium box I made some wooden dividers for all my glue, wood fillers, and caulking.
Makita makes some of the older-style boxes with 4 latches that often go on sale for very cheap on Amazon, but I prefer the newer T-lock boxes because you can open a box even if it's in a stack. But the T-lock boxes are insanely expensive, so I mostly have the Makita boxes. Both styles are compatible with each other.
