So you are wanting to match string that only have the domain, with no forward slash at the end?

Can you more clearly show which of the above 6 URLs should match, and then explain why that is the case?

You are only wanting to match strings that contain the domain only, then you can use something like this:
^(?:https?://)?(?:www.)?facebook.com/?$
This will match regardless if it has the protocol (http(s)://) and regardless if it contains www..
See it live
Breaking down the regular expression, ^(?:https?://)?(?:www.)?facebook.com/?$
^start of string
(?:https?://)?a non-capturing group that will match the protocolhttps?://, zero or one time?(optional)
(?:www.)?non-capturing group that will match onwww., zero or one time?(optional)
facebook.comwill match the domain
/?will match an optional?forward slash/
$end of string (emphasis added) - this is what allows this to work with your requirements as this will not allow anything to match after the optional forward slash in the prior bullet.

next unless !defined $url->scheme or $url->scheme eq 'http' or $url->scheme eq 'https';
next unless defined $url->host and ($url->host eq 'facebook.com' or $url->host eq 'www.facebook.com');
next if length $url->path and $url->path ne '/';
