I've had mine on a ceiling drop for the last 24 years in 2 different shops. Yeah, a floor receptacle would be better, but if the concrete is already there….... Anyway, put it just to the right to come down just at the end of the right side extension (or close). If you happen to add DC later, that's probably will it will be as well. The only thing this has interfered with (for me) over the years was when I had my router table in the right extension. I moved to a dedicated RT which solved that. I'd have a twist lock receptacle put in the ceiling to hold the plug.
