I LOVE threads like this. I embarked on a similar journey a couple years ago when I went on a mission to actually setup my shop for efficient workflow and organization because, like you, I had limited time, and wanted to get stuff done without spending 50% of projects just shuffling stuff and tools around. It's tough at the start, but gets easier, and is SO worth it. There's never enough room, but do what you can with what you have. I wish I had more separation between dirty tools, and clean tools, but it's not that bad.
I tried sketching stuff out, at one point years ago had some 2d cad models of my machines to figure it out, but in the end just did it the old fashioned way with a tape measure and eyecrometer and just moving them around, and figuring it out. Took a couple layouts at first, but the current one functions pretty good for the small space. One thing that helped me out a lot was those cheap shelf brackets and plywood scraps. Just getting stuff up off the floor, benches, machine tables etc and in a spot on the wall allowed me to keep moving forward. Being cheap and temporary they went up quick, but were easy to change around as the space evolved. But without them, I just seemed to keep doing that dance where you pick something up, turn around and set it down, then do it again a couple days later.....Making a spot for stuff, even if temporary kept the ball rolling forward. Once the big stuff fell into place, I could go back and refine those smaller areas and shelves. They're still a work in progress in my shop, but turn into fun little weeknight projects sometimes.
You have a nice space, and some cool tools (love that roller). I'm looking forward to following this one and see it come together.
