Google is notorious for that, their Google Play Services is particularly malicious because it significantly hurts battery life. Disabling it would help a bit, but it isn’t fool-proof because some devices don’t work correctly without it. “Uninstalling” Google Play Services is probably a bad decision because bootloops are possible due to the integration of Google Play Services on most Android devices. Facebook is a relatively easy one though, using AppVaultX+ Shizuku you can “Uninstall” those applications, unfortunately they’re not entirely removable, if there was a way to rid ourselves of it without just uninstalling it for a single user it would be nice and the space saved would be noticable.
