Storage facility lighting control

Good morning everyone. I have a question regarding the best way to control the lighting for a multi story storage facility. The lights in question are 4 ft LED surface mount fixtures. Cooper SNLED I belive. This is our 6th one for this company and I am trying to help streamline things. Previously the plans on the others called for many, many RAB LOS2500 sensors. At each end of the hall, middle of halls, doors and elevators. This would control a limited number of lights where the customer walked. The issue is those sensors are a total pain in the ass. If they are close to AC equipment they trigger constantly. Adjustments needed every summer and winter. If the 3rd floor of the metal building gets to hot, triggers sensors. Also, despite RABs insistence otherwise, when power flickers they get stuck in the on mode and need resetting.
The owner has asked for a better solution and I'm considering using 1 or 2 at the elevator and emergency doors to control all the lights on each floor. When we switched to the LED fixtures a few years ago out of curiosity me and my other electrician tested about 30 of these fixtures for load. We were shocked. We could essentially put each floors lighting on a circuit for the LED lights and emergency light on another and still have load to spare. We have never tried it because I've always separated the floors into 3 circuits for lighting (front, middle and rear) and it's sort of stuck in my head that this is the way.
Any suggestions or advice? Thanks!

Try a different mfg of motion sensors, Leviton or Wattstopper. Ask them to help with product selection and layout

I would probably design this space with some of the LED lights constantly ON as nightlights, so there will never be a situation where someone could be stuck at the end of the hallway without any lights on, and have the rest of the fixtures switched by occupancy sensors depending on how the building is laid out
