Running Ethernet to a Building within a Warehouse

Pictures for reference

Hello, r/networking !

I'm currently working on overhauling the network for a small business (Auto body shop) that has an abandoned security system and terrible wiring practices (Staples, zip ties tied too tight, running near electrical conduit, etc.)

I've purchased a Unifi system, and have already configured their network wirelessly as I prepare to run new CAT 6 (STP) and hardwired everything else that needs to be on a temporary basis.

The setup is as follows:

• Comcast WiFi Modem (being replaced with Netgear CM1000)
• USG
• Cloud Key Gen2 (with a 5tb Barracuda HDD)
• US-24 (being replaced by 250W variant for PoE phones, APs, and Unifi Video)
• Patch Panel
• UAP-AC-PROs (they have three separate buildings to cover)

I have other equipment to expand with but need to have the purchases approved first. My main concern is how to wire all of the cables to wall jacks correctly. I wanted to avoid running wiring across the back walls of the warehouse initially, as there is a bit of high voltage conduit, but the shop manager doesn't like what I'm currently doing (see pictures).

Even if I do run the cables against the wall, I don't feel comfortable running the cables from the wall to the top of this plywood roof unless it's secured or in some kind of conduit. On top of that, most of the outlets I have to route to are housing both Ethernet and wall outlets, and some are on interior walls that are in the middle of this building-within-a-building. For the record, I will be using shielded keystone's and a shielded patch panel.

The walls and roof of this small building are drywall > fiberglass insulation/2x4s > plywood, not plenum space

In short, I need to know the best way to route these cables discreetly, avoiding laying them on the plywood "roof" and be properly grounded.

If I have any incomplete information or you need more info, I will update my post after clarifying directly with you. This is my first post here so please be gentle!
