If you saw TFA and thought "hmmm yes, I know some of those words", then I can recommend the author's own lecture series on YouTube [0]. It's an intro to and overview of category theory aimed at programmers, with the requisite context and motivation for why anyone should care. It's long but worth the time investment IMHO.

  He also has an excellent online/PDF version of the material[0]. All of it is really mind opening stuff, and fun!

this has a real "a monad is a monoid in the category of endofunctors" energy to it

  > To understand actegories, let’s start with the definition of a monoidal category
  Definitely not written for someone with my starting knowledge, haha.
