Backup not listed to restore from on new Android device
Summarizing from comments ; 


OP has been unsuccessful in restoring from Google Drive trying the solutions linked in the question
Using  titanium-backup is not an option  as bootloader is unlocked on the old device but on the new device Safety Net would be tripped if unlocked and rooted, apart from wiping data
Only option left is to take a back up as explained here (using adb} How to fully backup non-rooted devices?. It has limitations so it's recommended to understand and test it out
