May I suggest Julia? Efficient and capable of (Common Lisp style) abstractions. Unsurprisingly, there are more than a few quantum projects in the ecosystem already.
I've used Julia with Pluto and Weave to create engineering calculations and reports when I was working at an engineering company, but I want something more general purpose. I've used CL for little scripts and utilities with Portacle, and I find I am more comfortable with the Lisp way of doing things. I had used Mathlab before, so Julia's syntax is very familiar. I do like the Models.jl library.
