Sitting in the middle of the shop as an all purpose bench precludes this as any form of standard woodworkers' bench. It will eventually be used for assembly, parts/tool holder, perhaps an outfeed table, and so forth. If truly 4 x 8 (that is some hunk of expensive butcher block) it will likely have on it more than one project at a time. It is also likely that it will be exposed to glue, paint, stain, varnish, oil of all types, greasy grime, cleanser, hammer strikes, chisel gouges, and whatever else. Are you sure you want the BB (edge or face grain) to be exposed to that?
I have two primary work tables. One serves as the table saw outfeed table. It is an old formica office work desk with two pedestal legs. It works great, and for the $5 it cost, it was a no brainer. I added wheels and spacers to raise it up. This table takes on most woodworking projects. In the pic below it is being used for another "random" project, this time the repair of a car top bag. It is aso to store the miter station. The next table is an old steel tanker table (not desk), that is 32" x 60". Removed the crumbling vinyl top, replaced with a sheet of 1/4 steel. made a rolling base for it with shelf. It has two drawers but I never use them, the the shelf is indispensable.
With that said, a huge BB table in the center of the shop would be a proud showpiece.
