Temporary Containers is a bit clunky, but it achieves the same goal using native Firefox mechanisms, so I assume that it works for ETP Strict too.

Thank you. I'm trying to understand how it works :)
i use temporary containers, might be slightly different from what you expect but it works very well for my usage and i recommend it
Thank you! Looking into it. To be honest I still don't quite understand the idea behind it – I'm reading here and there to try to understand better.
This is almost certainly what OP wants.
Cookies are just one kind of persistent data. And some sites intentionally disrespect boundaries.
I've used the forget me not add-on and didn't have any problems with it so faar, not sure about strict mode though. Its mostly been set and forget for me
Thank you for this suggestion. It looks good, but I see that its last update was 6 years ago. Sadly all or most extensions with this kind of functionality seem to have been abandoned...
Haven't tried it myself. As far as I know there is no way to do this in Firefox outta the box or with any setting.
To do this, I’ve used – for years – Cookie Autodelete. But I’ve discovered now that it doesn’t work with Firefox’s Strict Mode (the extension says “strict mode is not supported”).
fwiw, there are extensions out there that do the same things that strict mode does so it's possible to use them along with cookie autodelete -- that's why i do.
