And your #1 choice is "Zengo"? To start, cellphones are terrible for privacy, but worse than that, the website is filled with buzzwords that are typical for BS-sellers that try to convince gullible people. I wouldn't trust them with my funds!
If you want privacy, use Bitcoin Core with Coin Control through Tor. To add security, set it up as watch-only online wallet, and sign offline.
There's no need to trust or even pay third parties for this.
Absolutely.
Zengo looks shady IMO.
I am not familiar with "MPC wallets", I will check it later more in details, but I personnaly appreciate a lot to own my private keys.
It looks like they want to propose the exact opposite of the essence of Bitcoin itself:
TL;DR: “Not your keys, not your coins” has resulted in over $100 billion lost or stolen since the early 2010s. Zengo is the leading MPC wallet that secures over 1 million customers. Check it out, or read below to learn more about MPC wallets.

I am not involved in Political stuff in general, I don't care about that. But when it comes to privacy, the State of Israel is not working in user's interests IMO. Which GPDR policy is protecting their users ? Isn't Israel know for building a lot of shady
softwares stealing people data?
So, I should : give my email address, potentially a biometric data of my face, and others things (IP, communications etc..) to a company located in a country known to abuse of people's data ; all these things to "protect my BTC" from being lost or stolen?
Maybe I am ignorant, but I will stay with Bitcoin Core, Electrum, Trezor (and Tor). Open-source rules
