Did I mention this Sandman telecom installer web store?

Back when Mike Sandman was still running the place it used to have a lot more unique tools and products for telecom and related wiring. I suspect you might find some of their tools and tips helpful. There are also several install tips videos hidden way down at the bottom of that page.

One tool that seems to no longer be offered is a slingshot rig that fired a thin ‘string’ across the open space above a tiled ceiling (typical office ceiling). Open up a ceiling tile at one end, aim way across the space and shoot the tethered ball quite far. Then attach the actual cable(s) and pull it back across.

Much faster than using fiberglass rods. Although some of their rods are quite nice.
