High mobility career suggestion?

Hi! I'm currently in high school and starting to think about my future career. One thing I know for sure is that I want to live and work in different countries throughout my life, maybe staying in one place for 3–5 years, then moving to a new country for a new job.

Because of that, I know I probably won't go into region-specific careers like being a doctor, lawyer, or maybe even an accountant (since I’ve heard accounting standards can differ by country).

Do you have any suggestions for careers that make it easier to move between countries and still find good job opportunities?
