As far as the system updates, I don't know of a way except to do it manually. If you see the notification, turn off mobile data and force it to use Wifi. When updates are complete, re-enable mobile data.
I would look under Connections and then anything involving Data Usage. OS updates are usually quite large and my phone will let me know there's an update but won't download it until I'm on wifi. It came default this way.
