I can see not wanting to move to a temporary location, kids & all.

Do you have a current job now, that you like? Beyond the flight instructing? What about trying to hookup with a nearby University that provides flight instruction? Many seem to be looking for CFIs, even if you didn’t go through their program.

Ballpark age? You really should be racking up flight time now, 50+ hours a month. CFI hours are quality hours.

Nothing wrong with cargo, but cast a wide net. For pilots that wide net also means willing to go where the better job is, within some reason.
