There's a huge thread about workbenches shown here:
https://www.eevblog.com/forum/chat/whats-your-work-benchlab-look-like-post-some-pictures-of-your-lab/I've not shown mine in that thread though...
I think the way a workbench is arranged is a very personal thing, and over time it will change and become more suited to the person who uses it.
I've learned a lot about what matters in a work area both at work and at home. I have a few rules I learned in my first job and few newer rules I have set myself. This is because (in my case) there is limited space available both at work and here at home. So my bench layout is quite different to the majority of the ones in that thread.
I think that it's important that the workspace available should mainly be for the benefit of the user, not the test gear. So I keep the amount of test gear (and tools and components) to a minimum on my bench. No tools or component drawers are allowed to live full time anywhere on the main bench or its shelving. No cable racks, no PC keyboard, no monitor allowed as they take up too much space. I use a tiny EeePC netbook to control test gear or get data from it. On the rare occasions I need a better PC, I have a large Win 10 laptop I can put on the bench.
My need for space (to work efficiently) should be the most important thing in the workspace and not the need to cram as much test gear or tools or components as possible onto the work bench. So they all get crammed away in storage and only get to visit the workspace when actually needed. This strategy gives me the most space to do stuff. If you look at the benches in that thread above, a lot of people end up working in a tiny part of the remaining bench area because they crammed all their tools and test gear and components within arms reach. Some of them hardly have room to put a book on the vacant bench space.
