Last I checked, which was honestly two or more years prior, CloudFlare doesn’t handle second level sub domains (I.E. a.b.domain.ext) properly… when I tried it, I could make the DNS records, it did resolve, but the certificates didn’t work. I don’t know if that has since changed.
Totally, you can easy do *.test.yourdomain.com and that’s works just fine for certbot. Ive never used cloudflare so I’d assume the same setup should work.
You’re right but you can get a wildcard for that level as well.
