If you don't have an initial wire installed you can use a magnet kit with a specific wire to pull it through the conduit.(e.g youtube "magnepull"). A camera small comes in handy as well.
If you need to pull wires through the ceiling and you already have recessed lights you can use their wires to pull your new wire.
Unfortunately, in my experience of 6 or 7 new builds in the last 15 years or so, coaxial cables are usually staples to the studs and useless for this purpose.
Well, that's part of the fun/job. Usually you end-up with a few holes as well so you try to get hold of anything that helps you, "one inch" at a time.
As always, the easy way to deal with this is to let someone else do the job(hire a pro/custom installer).
The biggest skill is you have to hold your jaw just right when you do it. Then, it’s a piece of cake.
I know that Verizon also has fiber with a stiffer jacket that they can push through conduit a pretty good distance. I know this because I helped the Verizon installer run FIOS at my daughter's apartment in a building that was over 100 years old. The conduit had a crimp in it so it took the two of us a while to get past that.
