Ask HN: What's the best economics material for begineers?

I am new to Econ. Engineer by profession. Goal is to learn more about econ as a hobby/interest and not necessarily as a profession.

There are many sub-branches of Econ. I don't know which is my favorite. I do enjoy material on behavioral economics that i've read.

I've read books like freakonomics, superfreakonimics, voltage effect, the why axis, and thinking fast and slow.

Would love to dive deep into in. Looking for the following recommendations in all branches of Econ:

* MasterClasses * Youtube or course material * Books

Thanks
