adb uninstall will cover your needs and if you are using a banking app they won't let you use them if you root the device. So even if you choose the root way, it's recomended to relock root once you're done.

Also not sure about stock ROMs but be careful with core apps. For example, in LineageOS if you remove file manager that way you bork the system because any other file manager use the initial file manager.

@GravityAce You can also use the #UniversalAndroidDebloater. This makes it easier to get rid of the bloatware: github.com/0x192/universal-and…

the ADB method only removes the app for the current user. if for some reason you add another user on the device, all the apps will still be there for them.

Adb is just as effective as root for just disabling the apps for one user. As you said this won't free the space fully. Keep in mind you might softbrick your phone by uninstalling something unsafe.

The first thing to consider is what you want to archive. Security and privacy are not the same thing, however go hand in hand. With rooting you can go deeply into your systems setup, however it also opens potential threats against you. Adb is more secure. When it comes to privacy consider also rethinkdns or any other firewall. You can block internet access to specific apps and even system apps.
