As someone studying Polish, and making excellent progress, I mostly agree with your take. If you want to explore other languages, something like Spanish will get you much more mileage. Polish is difficult and the community of speakers isn't exactly warm to foreigners or people acquiring the language. On the other hand, if you truly enjoy languages and are passionate about them, I have found Polish to be really interesting and beautiful in its own way. Definitely not recommended, but still enjoyable to read/write/speak.
