My shop is about 26x60, with truss roof, so there are no support columns necessary.
I installed two 6x6 columns which are not structural, just to attach the DC, and electrical to. My big tools are clustered in the two columnar areas, with twist lock drops from the ceiling. There is a cluster of twist locks near each column which has at least one 30A 220, a double 20A 220, and a double 20A 110. Each also has a 12G cord reel nearby.
Picture a cluster of Sawstop cabinet saw with outfeed table, DJ20 jointer, 735 lunchbox planer, and medium duty 220V shaper. All around one column.
The other has a MiniMax 300 Combo , bandsaw, and portable tracksaw setup that comes and goes.
The columns also hold up track saw tracks, and my 4' long Kreg jig setup.
Only cords on floor are temporary.
Other tools, like RAS, router table, sanders, and miter saw are wall located.
