But on the other hand, it's been hard to put my finger on the tangible benefits of all that time spent on Haskell. I'm worried that I end up going deep into that rabbit hole without really benefiting from it.

I think that's fine, as long as it's your own decision from your own experience. On the other hand if you're struggling with anything in particular then we tend to be friendly and helpful over at https://www.reddit.com/r/haskell/. The monthly Hask Anything threads might be useful for you.

I've posted questions there before but unfortunately got no replies. However, some friendly folks at Slack helped me a lot.
