If you don't understand the cryptography enough that you have to ask about telegram, just use Signal. It's the best designed app for the security of most people, it doesn't have any privacy/security footgun, and has a pretty good threat model while not cutting corners on usability.

There's no debate. The CEO is a compulsive liar who misleads people about how encryption works. Every one who knows how encryption works and have looked at Telegram will tell you Telegram is not encrypted

Signal is well designed enough that Jurisdiction doesn't matter much. The only things you'll find that can br arguably better than signal are fully decentralized apps that go over TOR like Briar or Simplex but these have a lot less usage because they're so slow and terrible for your battery.
