I think it depends on how you want to get involved:
L1 protocol stuff? Definitely C++ since core is written in C++. However, with Python, you can also improve the core test suite.
For L2 protocol stuff, I think Golang or Rust are good candidates (LND is written in Go, CLN in C/Rust)
If you just want to build applications like SN, you can use any stack basically. SN uses NextJS + Postgres.
