All my local files are gone after 'Desktop and Documents' iCloud sync

I read the first article you listed above and found this might work??

Recover deleted files

If you need to access a file that you deleted within the last 30 days, follow these steps to get it back.

On your Mac

1. Click Trash in the Dock.
2. Select the file that you want to keep.
3. Drag it to the desktop or another folder.

If you delete files from your Trash via the Empty Trash option, the files can't be recovered

On your iPhone, iPad, or iPod touch

Learn how to recover deleted files in the Files app. 

On iCloud.com

1. Sign in to iCloud.com.
2. Go to iCloud Drive.
3. In the bottom-right corner, select Recently Deleted items.
4. Browse the list of files.

You can also go to Settings > Restore Files. After 30 days, files are removed from Recently Deleted and Restore Files.

Hope this helps
