It seems to me that you clearly like the idea of living home, but at the same time you still have some “energy” to do an experience abroad to progress you career.
My only question would be: is that A320 rating EVER going to get you home?
If jet life means living away indefinitely I’d go for the ATR probably, otherwise a few years experience abroad might be worth the effort to get you back home in a better (professional) position, albeit a few years in the future.
