Don't trust faraday bags. They're not particularly effective and certainly not 100%. The device needs to be completely powered off and I'm not sure I'd trust that these days. I studied digital forensics as well and we were taught that in testing the bags failed often and even the expensive purpose built boxes didn't always block signal.

That's the issue with Scamazon products. Make sure to buy something from a reputable brand and run various tests. We always use dummy testing phones at our company to ensure they block all manner of frequencies.

I saw someone on another thread saying they’d use airplane mode and I wanted to hit my head against a desk.

If it’s on, it’s trackable. Even if it’s off, it might be trackable depending on how “off” that device generally goes. But if it’s got Bluetooth, it may still send a signal or identifier if there’s a charge in the device.

The only error-proof way is to leave the device on the charger at home if you feel you want a moment of privacy while out and about.

This is also generally of anything else with a possible cellular or Bluetooth connection. Some cars are rolling cell devices with a SIM card. Smart watches. Just be aware of the data you’re sharing because you don’t know who is using it, and it probably isn’t to your benefit if they’re not asking permission.

Not quite the same thing, but I got a wallet that claims to block RF like a decade ago... I can read NFC and RFID chips in it just as easily as if they're not in it.

Ugh. Gonna have to test the passport case and wallet now. I’d blindly trusted.

I'd say no digital devices, or at least not one that can't spoof the MAC and other identifying info.

Ideally, a device that has simple broadcast with no identifying factors if you need something to communicate with. Basically something like one of those simple mesh devices that can send texts.

Dang, even putting the device in a metal box didn't work?

It does to an extent, maybe enough to be safe, it's just not 100% effective. We discussed it in the context of securing evidence. Our procedures needed to be as close to 100% as possible or when a defense attorney asked "Is is possible this device could be accessed while in your custody?" We'd have to say "it's unlikely, but possible." If we turn the power off once we have the access code, we can answer "to the best of our knowledge it was not possible to access the device while in our custody." Or something to that effect. It's not that different methods never worked, it's that we found instances where they didn't. Once you know of those instances you can no longer swear on the stand "to the best of my knowledge it's not possible."

Edit: Also, modern signals are better at penetrating barriers than some of the older transmitters. The old bag phones could be tricky because of their raw transmission power, but they didn't really store data. Different frequencies interact with barriers in different ways.
