My primary email is on my domain that's firstlast.com, so I purchased a random one and use that. Used with Fastmail I typically register as [e-mail] and it all forwards automatically.

1Pass+Fastmail will automatically generate forwarding random emails, as will Apple now. I prefer it coming to my own domain though to retain control.

Other details I frequently just make up (name, age, address), unless they're necessary for the service. eg. shipping needs my real address.

I wish there was a phone forwarding service that could randomize the number, similar to the Hide My Email that Apple does. I have a Google Voice, but that's a single number that can't be easily changed.

For things like supermarket rewards that just need a 10 digit number, I've thought about changing them all to 111-111-1111 or something similar. All I want is the real price of goods, but that needs an account of some sort.
