It can be a little esoteric if you don’t have experience with the paradigms, but I’ve never used a language that felt more free.
On SBCL you have typing support, CLOS provides an OO interface, and it lends itself well to functional style programming (despite not having a type system as powerful as say Haskell). Additionally, the ecosystem is quite stable and mature, any library of functionality you might need is likely available.
Common Lisp!
