To be honest I wouldn't use 1/8th of a bench surface with a tool cabinet (plus the opening drawers in front). It's like having a micro-wave oven on the kitchen work surface. Looks good on a plan but you lose a quarter of space offered.
All my common tools, screwdrivers and spanners are on an open shelf, roughly in order, to one side and always readily available.
My opinion only, of course.

I'm not trying to find fault. It's just that I put my bench under the garage window (for maximum daylight) which opens inwards and if I want to open it..........
Sorry another thought. Cables in the middle of the bench are really a problem. Same reason as they take up working space. Too late to put a socket at either side maybe?
