First off, as Boomer mentioned in his video, you should start off with way more simple concepts than that. For example if you think you have to differentiate full SH and 3handed tables, that just shows you have much less understanding of the matter than what you think you have.
Preflop in itself is a really complicated area, since there are 3 difficult streets left behind, and finding anything remotely useful for this type of analysis requires you to understand all the postflop concepts that can come into play.
First off I'd suggest going through the possible decision in a hand (or lines if you're more advanced) tying them together with EV and equity - how they relate to each other and how they are the foundation of every one of your decisions.
Also, never start with looking through HHs or small data. Data is really hard to analyse, and you'll get sufficient sample on good regs by datamining only, that is biased, since it doesn't show mucked hands. (Also even SD hands are biased, since you'll fold weaker hands more often postflop.)
You have to start with theory always, building up everything from the fundamentals and premises, and then fine tune-ing it.
I hope I could help, if you have any questions, let me know.
