TemporaryStorage: ZODB.POSException.POSKeyError: 0x83

Wouldn't it be helpful to add the "Transient Object Container" to the SAFE_TYPES? See plone.protect/auto.py at f2016f5d3b9d0ee071fa442cc5e818da760bb4fc · plone/plone.protect · GitHub

Or make an other case for the object at path /temporary_storage/session_data? See here: plone.protect/auto.py at f2016f5d3b9d0ee071fa442cc5e818da760bb4fc · plone/plone.protect · GitHub

Or is it better in general to use a dedicated storage engine for that? For example I remember beaker.session. Or what about a redis backend?

I understand that the session object is deprecated and should not be used but sometimes it would be really helpful to store some data not visible to or editable through the user. In our product we also could store the data in the user object itself. That could be a bit more comfortable between logins but also requires writing data to the main storage.

If you really need sessions, then use collective.beaker (with a backend of your choice, memcached or redis preferable). In Plone 6 TempFolder is gone anyway.

It would not be enough: besides the container, you would also need to special case the session objects, the objects used to implement the session timeout and any (mutable) objects you put into the session.
