Further resources on category theory

Question

I'm currently looking for sources on category theory that take a more intuitive approach and delves deeper into the nature of the idealogy leading to the theory.
I read some elementary books on the subject such as "category theory in context" but in my point of view, category theory seems like a more fundamental theory than most of modern mathematical fields.
Although I didn't feel like I got to the nature of the theory yet. So I was looking forward to find some books that take a more natural approach on the subject. (I apologise in advance if my description was not straightforward, I'm looking to find books taking an approach similar to ones Hatcher takes for algebraic topology, Bourbaki takes for absolutely anything and specifically algebra and group theory, Shahshahani takes for manifold theory and so on and so forth)
Any help or hint or suggestion helps. Also anything related to category theory (or universal algebra) would help a lot. Thanks.
