Have reloaded shotshells for years and my 38" high bench is fine.
Have just about all my equipment for metalic rifle reloading in.
Looking at the press and things like scale and powder measure, it seems like a taller workbench is in order. I'm six foot tall.
Any sugestions.

You and I are about the same height. My bench, for metallic, is 42 inches. I cut the 2X3 to 40 inches and put a 2 inch thick bench top on it. I built 40 inch by 20 frames, then screwed them to the wall and floor. The bench top is glued to the frames and screwed down. The bench top is 5/8th sheathing on the bottom with 3/4 inch particle board then 5/8th finish ply on top.
It's 16 feet long, 2 feet wide. The leg spacing is every 18 inches. The whole mess is painted in red concrete, floor paint.

My 300 pound buddy sat on it just to check the strength.
