I agree with those suggestions above, but one thing has been missed. If you not only need to pull wires through those holes, but drill them as well, you can do it with a single tool, such as this (https://www.altex.com/BES-38-x-72-High-Speed-Steel-Flex-Bit-FLX3872-P140505.aspx
). They make them in various diameters and lengths. They won't separate like those sectional ones that attach to spade bits and can be bent (not easily, but still can be done) to allow you to drill in the ceiling 2x4 directly from an electrical box sized hole in your wall (I've used their tool to route the bit up the wall while pushing down toward the floor with my drill since there wasn't enough room for everything to aim up because it was a short wall). It's often easier to drill from below through the wall than to use the various 90 degree drill adapters when space is limited, such as in between floors.
Once you've successfully drilled your hole, there's a small hole in the bit you can attach your wire or pull string to (obviously not with the drill rotating!!!) and pull the wire with. The 72" length (six foot!) is generally enough for most all needs. They make shorter ones if you need though.
There's also fiberglass fish rods (https://www.altex.com/BES-6-FiberFish-II-Kit-30-Total-Length-FIB207-P139816.aspx
) that are generally can be attached together for those very long runs or using a single rod for short runs. Those were a pack of six footers that will combine to make a 30 foot run if necessary. They also make shorter ones if those are more practical. You can even combine multiple sizes or packs to do nearly any job. They even make some that glow in the dark to make finding them easy in the dark space between floors. There are also various attachments (https://www.altex.com/Attachment-Kit-2-for-316-532-Rods-FIB565-P154816.aspx
) so you can use the end that works best for your needs job by job.
Now if you have lots of room and love to fish, these may be the perfect solution since they're like casting out into the lake. https://www.altex.com/Cable-Casting-Tools-Acc-C10903.aspx
