That’s an interesting comment, I had a similar experience going from Python to JavaScript then TypeScript, but now I’m really excited to pick up new languages (C, C#)
Yep, it gets fun after about the third language. This was the best thing about my programming languages course in college. We learned a bunch of languages a bit, while comparing and contrasting, which made all of them, and all the ones I've learned since then, a lot less scary.
These are all pretty similar though. If you want to widen your horizons, perhaps try a Lisp or one of the ML family languages (eh Haskell). These languages are actually different than the ones you used.
