I am sure answers to your question may vary.
"MY" personal opinion on this is at least ten miles once a week, you might get by with ten miles every two weeks.
There are several "Biggies" that you are trying to keep alive.
Not just "fire it up" and let it run, but actually drive it.
This will keep the all seals lubricated.
Your transmission will be lubricated
This will top off your battery. There are normal "all of the time" power draws in your vehicle such as radio memory maybe even computer/ security system draws. two to three weeks of not driving it might drag the battery down.
Tires will not "squish" in one spot (from sitting)
Ethanol fuel sort of separates it's water out when it sits still (this really rusted up my Jeep's fuel tank, when it sat idle for a couple of months awaiting parts)
After it reaches operating temperature, the cooling system components will "turn on" and operate.
Same goes for the entire engine, once it reaches operating temperature all of the little goodies inside and out actuate/ operate. This is kinda a workout to keep everything fit!
Brake drums and rotors tend to surface rust (or worse) if not driven to sort of keeps them scraped clean. Sometimes if they get rusty enough, they will squeak/ squeal/ make racket. Worse than that, nothing like jumping in and driving, the first time you apply the brakes It might near yanks you left or right off of the road as the brakes might 'Grab".
I am sort of basing this on the 1995 Neon I bought twelve or so years ago. I did not need it, it was too good a deal to pass up. Low miles/ Looked good/ Air worked/ 30 MPG. I gave $250.00 for it. I figured it would make a good spare car should one of the daily drivers fail to crank up. Unfortunately the step-daughter was "lent" 'Lil Red" until she could repair her vehicle. (This took her four years!)(what the heck, free car with insurance!) In four years time, I can say he still gets 30 MPG and runs fine. All of the original adjectives are out the window!
I found that two weeks was stretching it a bit, five miles did not charge the battery enough. Now it is take Suzie (My Beagle) for a ten miler once a week!
