I already left a couple of comments on the question in focus. I just read again your reply to my comments.
Current status of your question: It's too broad. I don't think that it's a good fit for any Stack Exchange site. You might need a mentor or you could make a self-learning plan.
At this time Stack Exchange hasn't an official or endorsed mentoring program.
You might ask for help with how to create a self-learning plan in Computer Science Educators. Ref. How to point "learners" to this site?
