I could run my two 120v branch circuits from one 12-3 cable and a
tandem breaker. Is there much
advantage to two cables and two breakers?

If you're running 2 120V circuits from a 12-3 cable, consider that the
neutral would have to carry twice as much current as it would in most
situations.

(This is not true. See my other post.)

So, if I understand you correctly, 12-3 cable isn't really intended for running
two 120v circuits, despite the fact that it's possible to do so. I did not
understand this.

Yes, it is. He's mistaken.
