Since I installed macOS Big Sur 11.1, I cannot see the usual folders in the left sidebar of Finder:
even though I have selected them in my preferences:
What is going wrong here and how do I fix it?

Next to "Favorites", if you hover over it, you should see an arrow you can click to expand the section. It must've been inadvertently clicked, since it's not new to Big Sur.
Drag the folder to the desired position in the sidebar. This adds the folder to the sidebar in every current and future Finder window, as well as Finder Open/Save windows/sheets.
Removal is done by dragging the folder from the sidebar out to the side.
Finder now shows documents belonging to some sandboxed applications.
No other application shows these extra folders. In particular Terminal commands and Finder replacements, like Path Finder and ForkLift, do not show the folders.
The folders are only present in Finder when an application has put data in the ~/Library/Containers/app/Data/Documents folder.
The applications I see in ~/Documents all have content in iCloud Drive though the files in iCloud Drive are not the same as in Finder.
In my case, I see the pseudo-folders for 3rd party applications like BBEdit, iThoughtsX.
This behaviour seems to be designed to mimic the behaviour of the Files application in iOS.
There is no known way to turn off this behaviour. But I would be glad to shown wrong on this.
It is not a good idea to just delete the folders or the files in them. Deleting the files is likely to cause problems when using the applications because the content has been created by the application.
My solution is to create a new folder ~/MyDocuments and put all my documents in there. That leaves ~/Documents for Apple to manipulate.
If you dislike this behaviour, submit feedback to Apple.
