Coldcard post anti-forensics for paranoid people
As you can see, the default firmware of Coldcard is hardcoded with values d13e and cc10. We are going to change it to make it look like a benign USB device, more on it later. First, clone the original firmware from Github: https://github.com/Coldcard/firmware We now need to edit the file called ./stm32/COLDCARD/shared/usb.py: COINKITE_VID = 0xd13e CKCC_PID = 0xcc10

Hardware/Software wallets and backdoors implemented by different nations?
Software altered? You were supposed to download from source and flash it yourself. So why did you alter it? No one other than you could have altered it! https://github.com/Coldcard/firmware

5 year old tails safe?
Consider holding long term with a solution like this. Have you ever use a hardware wallet like a coldcard

Is it safe to buy bitcoin on a fidelity account?
Coldcard has many other security features as well. You can find more about them online. Probably the safest hard & cold wallet on the market right now. But most people don't buy it because of their $400 price tag. But definitely worth it for anyone holding more than a pretty penny.

cex.io is holding my funds with no reason
Thus you will import the seed into a better wallet like https://bluewallet.io that can sign the transaction

Test transaction failed?
just use BlueWallet - https://bluewallet.io/ :-) I think it is easier than sparrow

Is bluewallet the way to go here?
Exactly this. Blockstream Jade hardware wallet used with Sparrow wallet on a laptop with linux, to make transactions. Then Bluewallet for a watch-only wallet on your phone device.

Why is it so difficult to pair Jade to the Green app?
I also use my blockstream jade airgapped with sparrow wallet on a linux laptop which I have been extremely happy with. You can also use BlueWallet for phone.
