I need instructions on how to package the software so that it can be automatically updated using the Windows Installer over the Internet and using local files as a fallback.

The diagram shows application can request a feature which is not installed during setup but is specified in the database to be installed just-in-time for use if required by the application in the future and can be from Internet. Does It work for you?
Just-in-time installation of an advertised feature installs whatever is in the initially deployed .msi file. If newer versions of those features are desired then just-in-time installation won't provide them since they are not present in the existing .msi file.
That's what I have heard about MSI before asking my question...
What you have heard is what Windows Installer, which does not support auto-update over the Internet, does.
So has your question been answered?
I cannot tell yet... Likely not yet.
So if you don't get the desired response your question has not been answered?
No, I'm just not experienced with MSI to make confident claims yet. Thank you for attention to my question anyway!
As far as I know Windows Installer does not support automatic updates over the internet for installed applications. You would need to create an .msi (or .msp) to update your application and deploy it to the systems on which your application is installed.
@A A Need a separate Windows Installer package to upgrade product. See An Upgrade Example.
