You might want to consider using Envoy mobile wallet by Foundation ^{the same team behind the highly secure Passport hardware wallet}.
Pros: fully open-source with reproducible builds, supports connectivity via TOR, capable to connect either to Foundation's node or your own one, packed with bunch of others features focused on both privacy and security.

The latest release is 1.8.6.

You can find the documentation and setup guide here.

You can use Electrum and Bluewallet with their own advantages.

Electrum supports Android, but as of now does not support iPhone (iOS). If you're comfortable using the desktop version, Electrum is supported on macOS.
Bluewallet not only supports Android, but also iOS. The desktop version, according to the bluewallet.io website, is supported on macOS, but I don't use it.

Why Electrum and Bluewallet, because these wallets are trusted by their users, especially Electrum. Both wallets are specialized in Bitcoin.
