Not sure if I fully follow what you want. But for my use case, I have something similar with cookie auto delete extension and container tabs.
The extension (not firefox) is set to auto delete everything by default. And then I can add a website-container pair to the extension's allow list and it just works
The only difference I can think of is that I don't bother with individual cookies, rather within the container, all the cookies from the particular website are allowed
Last I checked cookie auto delete I was not able to set say preserve cookies for example.com and only in the example container. Are you sure if you go in another container, those cookies will get deleted ?
Here is an example page
And I think for facebook the session cookies are
In the settings for CAD, there's a checkbox to enable support for container tabs. Have you selected that? It's under extension options
Ah !! Yes !
I think this is it !!!
Now I just need to figure out the session cookie name for every website, but at least it is possible !!
Nice!
Personally, I allow list all the cookies since the session cookie already identifies me anyway. So I don't see much point in the hassle of going more granular at the cookie level
