I had it in my head that sharing a neutral for two circuits was a big no-no,
so I never considered that option....

It's perfectly fine, as long as both of these conditions are met:
a) the two hot conductors are on *opposite* legs of the service, and

You know, I couldn't understand why so many people say make sure
multiconductors are on opposite 'phases' to protect the neutral
conductor. Figuring, ofcouse they will be opposite when using double
pole breakers. So, I wrote off the warning.

But as time goes on I hear from electricians they run into many times
homeowners tossing in two breakers, and only using the spaces
provided. Somtimes not having the breakers next to each(vertically)
but spread out in the panel. I've even heard about one homeowner
putting in mini-tandem breakers, and using that for a three conductor
cable.

So very good advice!

b) both hot conductors are disconnected by the same device.
Both requirements are easily met by using a standard double-pole (240V)
breaker.

Might want to post what you doing(or intend on doing) to get
suggestions how to do it best.

As it turns out, I found a better route through the house and have enlisted
a helper, so I'm going to KISS and run two 12/2 romex cables...

That'll definitely be easier in the long run, and less confusing to the next
homeowner.
