How are you using and configuring Firefox Multi-Account Containers?

Does it make sense to use Multi Account containers and Temporary Containers (in Auto Mode) at the same time with Librewolf/Arkenfox? (trying both of them out, haven’t decided yet) By default LW doesn’t store any cookies, I manually allow them for websites where I want to stay logged in + make their own container. Does my set up make sense or is it redundant? I’ve literally just discovered these two extensions thanks to this thread so I’m not really sure on howto use or configure them.
