I just try not to sign up for things. If I need a service and they need an email, I have a proton account. Don't use my real name. Try never to give my phone number. sometimes I give a phone number I used years ago. Still works!

Store stuff on the cloud? Ring doorbell with an account? Alexa? Heavens, might as well leave my front door unlocked and put a welcome sign out front for all passersby.
