If you intend on remaining single and childless for the rest of your life, and are perhaps a bit nomadic, then an expat job might tick a few boxes. If you want a normal, settled and relatively stable life, with the best chance for your family to grow roots (both geographically and morally), then the best (and frankly, only) option is to build a career with a decent airline back home. As the OP suggests, MONEY is the worst reason to choose a job/career. Chasing that through CX will lead mainly to frustration, misery and regret.
