I've really never needed an abstraction for semigroups, monoids, meet-semi-lattices, monads, comonads, arrows or catamorpisms in Clojure, Common Lisp, Scheme, or Hy.
These concepts become more relevant when I program Haskell, Agda, Isabelle/HOL, or Coq.
I'd say a stronger analogy can be made between reading MacLane's Catagories for the Working Mathematician and reading Hoyte's Let Over Lambda; you really only need to read a little bit of these books to get the core concepts. That being said, depending on what sort of functional programming you're doing, a strong background in category theory or meta-programming can enabling (or not).

That's fair. Although Haskell is a bit of an odd man out in that list, both in terms of its nature and in terms of its typical use case.
That being said, depending on what sort of functional programming you're doing, a strong background in category theory or meta-programming can enabling (or not).
This is where the analogy between the two books breaks down. When you're using a functional programming language as a proof assistant, category theory can be helpful. But this is far less common than meta-programming.

Functional Programming is a vast subject.
