Domain names for catch all email aliases (lemmy.ca)

I'm looking into getting some domains for email, so I don't need to use the same few addresses for everything. In doing this, the domain name itself becomes the identity, but it's also entirely arbitrary.

What is a good method to choose domain names so that they look more or less normal? Catch all addresses can of course be detected in SMTP, but the idea is just to not look suspicious. Would anyone be comfortable sharing the constructions they use? (though not the domains themselves, for obvious reasons) Should I use subdomains for the things that can safely be correlated, (as spam defense) or is it better to only use different mailboxes on one domain?

I just use a single catch-all account in my existing domain. If you send an email to my primary address it just goes to my primary box. If you send an email to my secondary address it goes to my secondary box. If you send an email to anything else it goes to my catch-all box.

Rumba@mycustomdomain.com Skips the catch only goes right to me.

Intel@mycustomdomain.com Go straight to the catch-all

I don't have to pre-make them I simply use anything that doesn't exist.
