I have no idea how to fix your problem.  I do use NM though, and my wifi
is already connected in the time I unlock after my laptop has been
sleeping overnight.

I use stable.

The UI I use to manage NM shows a "Priority" field for each connection.
My wired connection has a priority of -100, and the wifi has a priority
of 0.  It documents that connections with higher priority are
"preferred".  In the nmcli c show output, this is the
connection.autoconnect-priority attribute.  Perhaps you can see what
these values are set to for you and whether adjusting these improves
things.
