Nothing I can see there seems relevant, no.  I just see the messages
about when the connection is done.

It doesn't need to.  It can just presume that it's the case when
choosing what to try in which order.

I'd assume it would first look for "the network used most recently".
If that fails, it can then try other networks.

Same here (and I assume it's the same pretty much everywhere nowadays).

Yes, I know how to setup a static config but that's not what I'm after.

Debian used to do it more quickly.  Android does it more quickly.
MacOS does it more quickly.  What I see is a bug: there shouldn't be
a 20s delay before we try connecting to the wifi that was used before
the machine went to sleep.

I do use wired connections sometimes.
