I have a day/night IR game camera set up at the pond now - we’ll see what it catches...

#7 is right - cats retract their claws when walking. Canines don’t. (Can’t)
There are many coyotes in AZ. They always travel with the ‘family’. So, it’s probably not a coyote, if there is only one set of tracks.
Have you figured it out, yet?
