Electrical Interference In Warehouse Installation

I could use some advice on this one.

After exclusively dealing with residential projects only, I am now facing the next somewhat daunting step….my first full-fledge commercial project. The scale of the project does not bother me (~25 PoE cameras), but being that this is a rural, unconventionally built warehouse with HVAC equipment, refrigeration units, pumps, voltage panels, and even a VHF antenna on the roof, I’m a little apprehensive about the electrical interference factor.

I have read every article & discussion on IPVM along with other articles on the internet, but I still can’t quite pinpoint to what extent I should worry about shielding. Proponents of STP state its necessity, but then I read that STP can also be a detriment ("STP vs UTP for Surveillance"). Others say that using Cat6 cable would suffice, but others claim Cat6A in needed due to the added twists ("Cat5 Vs Cat6 Vs Cat6A Vs Cat7?"). I also read the discussion titled “Should All Security Wiring Be Run In Full Conduit?”, but there was no definite yes or no. Of course, I will take the precautionary measure of not running my cabling along side of electrical lines or next to large equipment, but in an environment like this one, there is stuff to avoid (to some degree or another) around every corner.

So, to what extent do you guys really worry about interference? Am I overreacting due to my lack of experience? Is a good quality Cat6 UTP enough? Although I realize it is tough to comment without knowing the specifics of the project, I would greatly appreciate any input.
