I really enjoy Ruby, Lua, and Lisp. I find it interesting none of them are really used a ton in industry, but I've written my own Civ V and Civ VI mods (and helped other people with theirs). Lua is pretty much a pleasure to work with everytime. Lisp is one of those odd balls, that is both prelevant, but also rarely seen in industry. My primary interaction has been with Scheme, Racket, and elisp. Wiring modes for Emacs is always fun (in elisp) and amazingly short, consise, and powerful. Ruby is a dream, mostly I use it for Rails, but the whole ecosystem is well thought out and worth the time (what little you need) to put in. I've setup websites at scale in Ruby on Rails, with components written in Ruby inline C to make it much faster, an NLP library and much more (https://projectpiglet.com/ https://projectpiglet.com/). Better yet, I've seen non-programmers pick it up in a few weeks. Honestly, when I hear someone is developing an app in Springboot (Java) or some other webframework, I'll often show them they can complete their whole app in a couple days with Rails.
