I use a wired keyboard for latency, FileVault, and reliability reasons. I’m not concerned about the security.
If someone is close enough to sniff BT packets, they can also do acoustic analysis of your typing, or a TEMPEST attack on the (plaintext!) USB protocol. BT can have about the same level of encryption as TLS. https://duo.com/decipher/understanding-bluetooth-security https://duo.com/decipher/understanding-bluetooth-security

What about the far more common wireless USB dongles?
