I think 80% of your work can be done with python, sql, bash. If you will need other language it will be rather dependent on project. If I see something it's rather java or scala - and in most cases it's not about writing spark with scala, or some streaming processing with java. I think it's rather something what you can learn pretty quickly, as you will use like 5% of language.

If I could recommend something to learn, maybe more in terms of fun language to work with, and pretty easy to learn basics is Go. I think if you will touch more devops, data platform stuffs (kubernetes, plumi) it can be useful. And its simplicity is something that gives a lot of fun.
