If, as others have said, programming languages count, I’d go for Cobol. As I understand it, lots of big banks still run on it, so there’s good money to be made. It would probably help me to learn other programming languages too.
If it had to be a human language, I’d be tempted to go for Russian or Arabic because of the potential threats, so translation opportunities, or Welsh. I’m Welsh, but really struggle with learning Welsh, especially when compared to French and Spanish.
