Everyone I want to talk to knows not to call me; I feel exactly the same. Phones used to be useful, but the sheer volume of telemarketers and scams have reduced it to uselessness. If it wasn't for 2FA occasionally requiring a phone number, I wouldn't even have one at this point.
You don’t always have a choice as it is dictated by the service provider, but whenever possible, disable SMS based MFA and enable TOTP or something else. SMS based MFA is susceptible to SS7 MitM attack.
Same. In the last few years (2-3 probably, I don't count) I don't think I have given it out anywhere. I just pretend to not have a phone number, and if people think that's weird I don't care, deal with it. Nowadays if a service requires my phone number, I don't need that service. Or in rare cases I'll try to find a free online number for receiving a code, but that's the only alternative I take.
Use an authenticator or Yubi key. SMS authentication is the worst possible method.
