If you have an identity section then the users section does not get used. The users key also goes under the user-data key. See https://askubuntu.com/a/1385096/376778

You don't need to create the root user. You just need to set its password. I've used this partial user-data configuration to set the root password. This should work for local logins (e.g. vmware console) but additional configuration would be needed to allow remote logins (e.g. ssh).

#cloud-config
autoinstall:
  user-data:
    chpasswd:
      expire: false
      list:
        - root:$6$REDACTED
