A cursory glance gives me this: http://www.cs.nott.ac.uk/~pszgmh/cat.html
Which seems to avoid being very "mathy" right out of the gate, though I can't tell its quality.
All lectures from the course are in this playlist: https://www.youtube.com/playlist?list=PLhgq-BqyZ7i7MTGhUROZy...
Milewski's free book Category Theory for Programmers is a "classic" as well https://github.com/hmemcpy/milewski-ctfp-pdf
In general you can find videos on youtube of talks given at various industry functional programming conferences that often help since they start from the industry programmer point of view rather than the pure maths one.
E.g. A practical introduction to Category Theory (for Scala devs) https://www.youtube.com/watch?v=GNG3Gk9KsoI
It is available here: https://arxiv.org/abs/1803.05316

I’d like to add a recommendation for the book Category Theory for the Sciences: https://mitpress.mit.edu/books/category-theory-sciences
Archive.org seems to have it for download: https://archive.org/details/cattheory
(I prefer the printed copy myself, i.e. it has been worth having.)
