I have really started to use the 'Hide my email' feature from iCloud. It's been so nice. If an email gets pwned, which often happens from a service I stopped using many moons ago, then I just deactivate or delete the email address. I imagine many other services provide this feature as well, but it's what's most convenient for me at this time.
Not sure I trust the longevity of some of them, though. I do use https://temp-mail.org/en/ or other similar services for some logins for some services I'm not afraid to lose access to, though (especially for places likely to spam me).
