Python for job orchestration (Airflow) and data science (numpy, scipy, etc) , Java 16+ for the general enterprise, product development, Julia for HPC. C for embedded, C++ for games, highly intensive systems.
Can't have a most employable list without mentioning JS. Personally I'd swap Julia for JS. Apart from that this list tracks.
JS for HPC instead of Julia?
No Rust, no Go? (Not that I am rooting for them)
Go maybe, especially for tooling, backend and ops work, from my perspective Rust will take a while longer employability-wise but probably still worth learning.
