I've used an old crate as a workbench for far too long- set it up 20 plus years ago and made do.
As it was in 2018
I looked at a few different workbench plans and decided a 3' deep X 8' long version would be best for the space and intended uses- I just got a dovetail jig from Rockler, cut a few test pieces and I'm about to start building drawers for circular saws, jigsaws, drill motors and the like.
Also just finished cladding the concrete subwall with 30 year old cedar fence boards
