Started using OpenLayers 2 weeks ago for a side project. Agree with you on power of OL. I just started basic features and already loving it.

Apart from OL API doc. Could you please recommend any book/course to learn both concepts & API.

Nope. Just read the source code. All the references I have seen online are outdated or aggravatingly incomplete.

Seriously. The nicest part about the source is that it doesn't lie.

It's rarely as scary as your anxiety tells you it's going to be. Even for larger projects. You got it, may as well use is.
