First, what's the point of this post? You mention few extremely generic areas of learning without any actual meat to it. What is the framework that you suggest?

Second, in my experience, learning depends heavily on both a learner and a skill being learned. Beyond some common sense observations (like learning by doing, having some plan, setting goals etc.) there is no point in generalizing and overthinking the learning process itself.

Because what works "on average" with hi probability wouldn't work for you (unless the skill being learned and you are both perfectly average in all relevant parameters).
