Something also to tweak to your needs and preference is when your phone should perform updates such as on mobile data vs WiFi, while charging, at specific battery levels, etc.
Go to Settings -> System -> System Updates and choose your desired preferences.
Populqr app installation sources such as the GrapheneOS app store, Play Store, Accrescent, Obtainium, Aurora Store, and F-Droid clients each have their own update settings located in each in-app's settings as well.
