You should try to rent a lens to see what works for you. I used lensrentals.com just to try out the 85/1.4 that "everyone" said was awesome. I loved it, but couldn't justify the price for a hobby, so I settled on the 85/1.8. I bought it years ago (4+) and I think I've taken less than 20 pictures with it. My "nifty 50" is still a favorite 50/1.8, but I also love the 70-300/4.5-5.6. Those two are my most used, and both were less than $600 US total.
