For efficiency, try to keep your fortress layout compact and vertical. Dwarves navigate staircases much faster than hallways.
I typically dig a 2x2 central staircase for my forts and then dedicate each z-level to one thing/industry. For example, I'll have one level for my main stone stockpile as well as my mason/stone crafter/mechanic workshops and then have my furniture stockpile on the z-level below that so they don't have to haul finished furniture very far.
