ive built quite a few shop work benches. my bench has 4x4 legs and skirted with 2x6 lumber frame topped with 4'x8' 3/4" ply. i threw a coat of varnish on it to seal the wood. well 45 years later, its still solid as a rock. ive overhauled engines, built furniture and several model ships. my kids used it for their projects and even played under it as their club house.
my smaller work benches are made of old solid core doors i got from dumpster diving. id build lumber frames for the undercarriage. some are on wheels so i can pull it out for walk around projects. some have drawers built in for tools. the doors are virtually indestructible. a nice 1-3/8 door mounts a wood working vice very nicely at the end as well. the door bench at my daughters house has a small craftsman drill press and a band saw bolted to the bench. the other has a radial saw. my router table is mdo for a smoother truer flat top. my work shop also has darkroom equipment... photography is another black hole hobby of mine.
how much space do you have and what tools and other uses do you expect to have in your shop?
btw for light, im using flat led ceiling lights i got at home depot. you can put smaller panels over perimeter work benches. the nice thing about leds, you can change the color temp from warm white to bright white light depending on what you are doing. a smaller spot lamp on the table can be moved around like an operations light focused on the work.
