Why doesn't anyone sell a standard HSS/spur/multipurpose bit this kind
of length?

I just walked into my local DIY shed a few months ago and picked up a
foot-long 3/8" drill bit off the shelf - wasn't expensive, either.

Or, as network cable's flexible, you could probably drill from both sides
of your frame with a shorter bit - you'll be able to get everything
*almost* straight with some careful measuring and the cable will have
enough give in it if it's not exactly spot-on.
