There are a lot ( a lot ! ) of MSFS tutorials on YouTube. For example, Tutorial #1 - Getting Started - Microsoft Flight Simulator. I found this one by searching for “MSFS beginner”.
MSFS has many settings and users have many different hardware/software configurations, so there is no quick-start one-size-fits-all config. I have decades of experience with most consumer flight sims, and it was still a slog to get through all the settings and tweaks to get it operating optimally for my circumstances. But it has been well worth the effort; it’s an amazing product.
