My shop is about the same size, had skylights put in the south wall so don't need lights during the day.
All of my power tools are on casters so they can be pushed together out of the way when not being used.
I started with two LED flood lights on separate switches, in the center, pointed away from each other. That worked well until I found a brighter, whiter all direction LED. It is a 14w, 1200 lumens, Ecosmart brand
I removed the flood for the front half of the shop, aimed the holder straight down and screwed it in.
It lights the whole shop. If I need more light for a project, I use a portable LED work light.
Here is a daylight shot of the south wall.
With the LED on, notice how it lights up the wall 15 feet away.
