@Cazares, Joel, Thanks for posting in Q&A. From your description, I know the Microsoft store and Xbox app game store is blocked which we can get the Microsoft Flight Simulator. You want to know if there's any other method we can install this app via Intune.
On my point of view, you can contact Microsoft Flight Simulator support to see if any msi file can be downloaded manually. Or if there's any exe file with silent install command.

If yes, then you can consider deploying it via Intune Win32 app.

Hope the above information can help.
