The cleaning fingerprint thing isn't unreasonable in some rare contexts, but thouching all keys on a full keyboard is where it really goes off into paranoia.

Disabling fingerprint biometrics at night...why? What's the risk you're worried about? Someone breaking into your house to use your fingers to unlock your phone while you're asleep? You can get hacked much easier without anyone ever being in your home. Anyone in your house can use Celebrite without touching you.

I'm a privacy and security enthusiast, and I agree, this sounds like the edge of needing to talk to someone. Theres a lot here that no one worried about their security would ever do.
