Especially today, since Lisp rather than being a single thing, is a family of languages. I mean, there's some truth to "JavaScript being a Lisp", so you can see that it's a bit open ended.
If you're looking for an embedded Lisp, then I would concentrate on finding one that simply appeals to you. That is, find one that integrates easily, or has a particular feature that you like, or any of many things that may catch your eye.
Once you pick one, then simply "learn that". Consider GIMP originally started by integrating SIOD (Scheme in One Defun), which is a simple Scheme interpreter. They have since moved on to TinyScheme (of which I'm unfamiliar).
But, SIOD has been around forever. SIOD begot SCM which begot GUILE, which is specifically designed to be embedded. It's also pretty large.
ECL, which stands for Embedded Common Lisp is, well, a Common Lisp. Scheme and Common Lisp are both Lisps, but quite different from each other.
That's why rather than saying "pick this", simply find one you like and learn that. The landscape is wide and rich.
