If you use a .local domain, your device MUST ask the mDNS address (224.0.0.251 or FF02::FB) and MAY ask another DNS provider. Successful resolution without mDNS is not an intended feature but something that just happens to work sometimes. There’s a reason why the user interfaces of devices like Ubiquiti gateways warn against assigning a name ending in .local to any device.
I personally have all of my locally-assigned names end with .lan, although I’m considering switching to a sub-subdomain of a domain I own (so instead of mycomputer.lan I’d have mycomputer.home.mydomain.tld). That would make the names much longer but would protect me against some asshat buying .lan as a new gTLD.
And more importantly the devices don’t, it’s very noticeable via wireshark. The only multicast traffic comes from Android, every other OS does not bother, ironically not even Mac OS, whom is responsible for the whole Avahi/Bonjour nonsense to start with.

Another user pointed out that .home.arpa seems to be reserved, thus hopefully protected from TLD hijack which is what I’m worried about as well. I’d make it .homelab. I wonder if one can restrict recursion on certain domains?
If one server is marked as authoritative, but to recurse for other things, will it recurse for it’s authoritative domain, or give NXDOMAIN?
I do own a domain name via cloudflare so I might just utilize that, but I don’t like it.

No it must not lol what? The RFC says “may”.
