That isn’t needed anymore, I think F-Droid basic can auto-update apps now. https://f-droid.org/packages/org.fdroid.basic/

The best option would be a Pixel running GrapheneOS. If you don’t want a Pixel, a well supported device with DivestOS (look for a recent one with a relockable bootloader) would be your best option. Debloating a stock OS isn’t recommended since those apps will come back anyway should the system update. Leaving your bootloader unlocked and rooting your phone as well is detrimental to Android security. Please don’t do that. See a third party OS comparison Also see:
