How do open challenges work?

I mean if I'm low on the card why wouldn't I try for a title or a high card guy? Who in kayfabe actually gets their music played and allowed to challenge who ever is issuing the challenge.

Also because I would be the worlds worst booker I would book some nobody to do an open challenge and have no one show up and the person leaves dejected. Also in the reverse too many show up and its a battle royal.

Title shots are very difficult to get in any sport, including boxing and UFC. If you have lost a previous shot and weren't particularly competitive, you likely won't be considered for another. If you're not a wrestler that is traditionally in title contention but believe you could be with more experience, it is not in your best interest/against the odds with more bad outcomes than "loses a match" to answer the challenge.

In Pro Wrestling terms, an open challenge is to anyone in the company or not, throw your name in the hat, and the champion can hand pick his challenger.

Rocky got his match with Apollo this way and more succinctly, AEW is doing this concept in masterpiece style with the TNT (and presumably the tbs) championship

I mean, it wasn’t an open challenge, but open for a second partner and Braun chose a 10 year old boy out of the crowd. So, I think they just are first come, first served.

To explain the backstage version, I imagine it's the first to reach a certain line outside the champion's dressing room door.
"You win, here's the details, give to the boss. Everyone else, stop by our head referee to have your parking validated."

It would seem the first guy to reach the sound truck to get their music cued up and make it back to Gorilla in the 26 or so seconds you have.
