Haskell - a general-purpose functional language with many unique properties (purely functional, lazy, expressive types, STM, etc). You mentioned you dabbled in Haskell, why not try it again? (I've written about 7 things I learned from Haskell, and my book is linked at them bottom if you're interested :) ). Source: about 3 years ago
Where you go is entirely up to you. According to haskell.org, Haskell jobs are a-plenty. sigh. Source: over 3 years ago

Haskell.org now has a big purple Get Started button that takes you to a nice short guide (haskell.org/get-started) that quickly provides all the basic info to get going with Haskell. It is aimed for beginners, to reduce choice fatigue and to give them a clear, official path to get going. Source: over 3 years ago
I just jumped into the wiki "Write Yourself a Scheme in 48 hours" which looks pretty good. (although some of the text explanation is hard to understand without context).. I used cabal to set up the starter project. Sublime editor seems to work OK and I just use the git Bash shell on windows to compile the program directly on the command line. So maybe this is all good enough for now (?). It seems installing... Source: over 3 years ago
Https://lean-lang.org/ If you can express a solution in Lean you can formally prove or disprove it. Formal verification is making a debut in traditional engineering toolkits. - Source: Hacker News / 12 days ago
This is what Lean is for: https://lean-lang.org/ If you have the LLM generate Lean code, and it compiles, then the proof is correct and you don't need to bother checking its working. (You still need to check that it is proving the theorem you asked it to prove). - Source: Hacker News / 16 days ago
Lean is a programming language [1] > Lean is an open-source programming language and proof assistant that enables correct, maintainable, and formally verified code [1]: https://lean-lang.org/. - Source: Hacker News / 25 days ago
This sort of theoretical result is not always as clear-cut as you suggest. Computers are finite machines. There is a theorem that although a machine with finite memory can add, multiplication requires unbounded memory. Somehow we muddle along and use computers for multiplication anyway. More to your point there is a whole field of people who write useful programs using languages in which every program must be... - Source: Hacker News / about 2 months ago
I don't know about running per se but practical applications (as in done for product/service) exist. A notable practitioner for Isabelle and Lean is AWS[0]. There is also TLA+ for a more practical tool. The most widely used variant of these proof assistants are probably formally verified compilers, like compcert, which are used in some highly regulated industries like aviation.

Rust - A safe, concurrent, practical language
Elm - A type inferred, functional reactive language that compiles to HTML, CSS, and JavaScript
JavaScript - Lightweight, interpreted, object-oriented language with first-class functions
Isabelle - Isabelle is a proof assistant for writing and checking mathematical proofs by computer.
Python - Python is a clear and powerful object-oriented programming language, comparable to Perl, Ruby, Scheme, or Java.
Agda - Agda is a dependently typed functional programming language. It has inductive families, i.e.
