I am in a similar situation as you, but in a lot of ways you're asking more sophisticated questions than me. FWIW, I've been building a little toy lisp-scheme like scripting language as a learning tool: https://github.com/zeraholladay/lispm/tree/main. It's been a lot of fun and I've really enjoyed exploring parts of CS that my career hasn't really taken me to.
