The reason the FCC is only allowing the sale of state approved routers in the US?

That would prevent cell signals from inside, making it harder to (e.g.) call the fire department, or an ambulance.

    That could be fixed by using WiFI calling, getting a VoIP line or installing a cell booster.

    WiFi calling will make a direct beacon to follow, as any other WiFi use would. Faraday cages would block WiFi calling, as with any other signal.

    I think these techniques can use the reflection of the signal from the AP’s own transmissions, no additional devices needed.

    The Faraday cage will keep the WiFi signals inside the building. Nobody will be able to track you from outside and your own trusted devices will work fine inside. Just don't bring any untrusted WiFi devices inside the Faraday cage.
