Thanks for your posting on Q&A.
When WSUS updates are approved, does WSUS scan the local system (WsusContent) first before going out to download the updates? Or is it the other way around?
First of all, Update Files and Languages configuration will be written to the database according to your settings. Here is the reference picture:

So, again, my question is, upon approving updates, does the system first scan the local source, then reach out to an external source (which is what I believe happens)? Or does it first try and reach out to an external source first, then failing that, look to the local source (WsusContent)?
There is no such document for reference, so it is hard to say. But in my opinion, the WSUS server will scan the local source first, then reach out to an external source.
In addition, I noticed that you try to run the export and import command to copy the metadata first, and then copy the actual update files from the connected WSUS server to the internal WSUS server. The order is wrong. According to this link, it is recommended to copy the updates from File System first and then export and import the metadata.
This type of problem can be fixed by copying the update onto the file system of the import server and then again attempting to deploy the update.
It seems that there are no updates for several day. May I know the status of the case? Whether the solution I provide above is helpful or not?
Please keep us in touch if there are any updates of the case. Don't hesitate to keep us in touch if you have any queaations.
Thanks for your time and have a nice weekend :)
