TinFoilHat I have removed the latter part of your post, we do not have aversion to people making claims so long as they are backed by sources and ensure this community resource doesn't push misinformation. I have also closed your other thread as it was following a similar pattern to this one, just with a different hypothetical question. Please refrain from creating any more in the same vain as I will consider it spam and you risk being suspended.
Regards the NFC and Bluetooth as well as the cellular radio/airplane mode, all standard toggles deactivate them at the hardware level.
In regards the phone number attack you were concerned with SIM swapping would probably be the most direct and well known. As advised in your other thread, upon restoring your accounts with the existing number, it would be advisable for you to change your number for the SIM and the accounts too.
If you wish to ask further questions please contain them here and provide evidence/citations/sources for any claims so that they may be addressed properly.
Other than that I hope you have a pleasant start to your journey as a user and find GrapheneOS to your liking.
Take care.
