Thanks for the thoughts and suggestions.
OK, so I've tried a couple of things.
Full reboot and set min protocol = SMB3 in smb-user.conf
Validated that it is being accepted using testparm, which gives
testparm
Load smb config files from /etc/samba/smb.conf
rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384)

From the Finder (gui), trying to expand the Wiz network node I get
URLs with the type “smb:” are not supported.
From CLI I get
mount_smbfs //beyonwiz:******@beyonwizt4.local/Movie ./junk
mount_smbfs: server connection failed: Operation not supported
Modifying min protocol to SMB 2 gets me back to the socket not connected message.
So progress, of a sort
Seeing the deprecation warning, I've comment out the null password option down in distro (yes, I know it will get overwritten) and it made no change to the results.
My next test is to swap from insecure to secure config.
