There is a lack of content and detailed training videos for newcomers to flight simulation in MSFS beyond the absolute basics. I'd almost recommend buying FSX, since it had a much more complete in-flight training section than this game does. Otherwise, I've started a YouTube channel to teach the skills newcomers need to enjoy playing the game. I'm not that far a long yet, but I plan on covering the questions you're asking in the coming weeks. Link is in my signature.
