Awesome to see you are on a quest to learn more. Aviation is a lifelong of learning and experiences. I’d recommend avoiding anything “education” related in the sim and focus on getting real-world general aviation learning content. There are reputable things that are free from the FAA (or your local aeronautical agency) and other sources, and, things you can purchase like the “King” series on Sporty’s.com.
Whether or not you intend to fly real-world, it will be a huge benefit to learn how things actually work. It will even make you a better sim pilot as you’ll have an understanding of how things are supposed to work and can better spot a bug or problem vs calling something out due to a lack of understanding. Your satisfaction level will increase as well.
There’s nothing wrong with getting your insight from multiple sources. My thoughts however are if you do YouTube, watch channels of actual pilots flying actual airplanes. Those learnings will translate to sim flying. And if they don’t, then you know you’ve reached a limitation in the capability of the sim.
I’m also happy to help so PM me if you’d like some recommendations on sources.
