I have an unusual connector, I know this cause I can't seem to locate a connector that will connect to it.
I know what it does but can't find a source to build my wire cable I need. I can find the board connector but not the mating connector.

As you'll find on the mechanical drawing for the part number in your image, the Molex 504187xxxx series mates with the Molex 5014186xxxx and in the 18 pin configuration that would be specifically the 504186xx's.
Generally we don't do sourcing questions here. But as an illustration of the process:
1) Find the technical documentation for the side you have
2) See the listed mating family
3) Find the part number with corresponding pin count and series.
Originally I missed the matching series notation on the drawing (I expected it to be there but didn't see it) and tried to do the cross reference by family name, but these are often not sufficiently specific, and as a result I spent a couple of minutes mistakenly wading around in the 505432xxxx's, which are something a bit different even though much of the name matches.
For a length of a few inches, twisted pair or not probably won't matter - ribbon cable will likely work just fine in most environments.
For option 2, I assume you mean something like this? (though probably with both ends female)
Those cables should work fine if you can find a source in the length you need - really short ones are probably uncommon though. The fact that those cables aren't twisted for about an inch on each end is why I suspect you'd be fine without twisted pairs.
Those cables are for 2 USB ports, and are keyed so they can't be plugged in backwards - so you could use one set for your USB signal, and the other for the GPIO pins.
