Shop Lighting advice wanted/helps with my employment. 3 bay layout, with GIANT I beams coming down lower than lights mounting location

Indoors:

40' wide, 60' long', back of shop 13' tall, front of shop maybe 18' tall

Bright, some suggested a few ?colored? LED shop bulbs that can be connected directly to conduit, not plugged in.

Owner wants BRIGHT light, mostly LED, bright enough to avoid much transition from walking in from the noon desert sun when you drop a bolt/nut and need to see it in a shadow?-he is worried that the 4 foot LED light bulbs that I suggested would be insufficient. I had suggested 8-10 bulbs, in pairs, a piece (or 16-20 total) for the two larger bays, and the third bay is half as wide so, 4-5 four foot LED bulbs

Two entry doors will each have three 3-way toggle switches, one switch for each of 3 bays as someone opens the entry door, they can turn on lights from either side

In addition, I am getting conflicting input as to whether this lighting should have 14 AWG or 12 gauge wiring

Outdoors, under a metal overhang, in a dry for 10 months climate, with 2 months where monsoon level rain can occur.

THANKS FOR YOUR HELP, TIME, and CONSIDERATION!!!!
