It is important to note that restricting all background data usage on android is not an ideal option if you’ve been receiving notification from specific apps such as FB.
If you restrict the background data of FB, you’ll not get notifications about new messages or updates. Only when you launch the app, you’ll get updates from FB.
Also, it is important to note that this option only restricts the background data usage of the cellular data connection. It means the apps will use background data when it is connected to wifi network.
