    Thanks for the feedback. I was about to dig up some old Smart Switch
backups (if any) from my backup disks, but as you've already found the
Wi-Fi settings data is encrypted, there's no point.

Passwords (and WiFi settings contain a password) are intentionally not
backed up or transferred to a new phone. This feature would allow a bad
guy to clone your phone and impersonate you.

 
   That would only work if the bad guy has physical access to your phone
*and* can get *into* that phone, i.e. he has to have the password/PIN/
fingerprint/etc.. That's exactly the reason why for example bootloaders
are locked, i.e. physical access is not enough to get into an Android
phone.
 
   So there's no valid reason for the legit user of the phones not to be
able to transfer the Wi-Fi settings/password (or other passwords).

 
Nevertheless, that is the reason.

  That Wi-Fi passwords are not backed up 1) is not true for Samsungs's
Smart Switch (see above) and 2) for Google Backup (to Google Drive) has
been more or less debunked by my response of earlier today:

  Hmmmm!? Strange! On my ancient Samsung Galaxy Tab 4 10.1" (SM-T530)
with Android 5.0.2, i.e. even older than yours, Settings says it can
"Back up application data, Wi-Fi passwords and other settings to Google
servers". (Settings -> 'GENERAL' tab -> 'Backup and reset')
</quote>

  But granted, that's about backup (and restore to the same device), not
about transfer to a new device.

  Still, the 'reason' for not transferring Wi-Fi and other passwords is
invalid/silly/<whatever> for the reasons I gave.
