#114: Tutorial: Common Emitter, Common Collector, and Common Base Transistor amplifiers
Why people recommend it
A W2AEW video comparing the three basic BJT amplifier configurations, recommended for understanding gain and why common emitter is the usual choice.
Watch for: Suits those who already know what a BJT does and want to understand amplifier stages
In their words
I recently watched this tutorial, and wanted a bit more elaborate explanation about why adding the cap circled in blue greatly increases gain.

I can highly recommend a W2AEW video for discussing at least some of the points in your question:
