My closest encounter with LISP was a long project with Wolfram Mathematica. Can you elaborate which tooling and set of "standard libraries" you use? I'm doing day to day work in Python ("batteries included") and reall would like to make the switch.
The language spec of Common Lisp is pretty large (not necessarily a good thing) so the built-in libraries offer a lot so you don't necessarily need much third-party libraries. Issue with this along side the size of the spec is the fact that the spec is old, so it's missing some crucial stuff from it like threading etc. in which these third party libraries comes in handy.
