I don't personally like or support the idea of overcomplicating the
configuration for a false perception of simplicity...

The BEST solution, in my opinion, is to generate static server blocks
for each known domain and regenerate configuration as needed (when a
new document root is created, the new server is created too).

Still, for the arbitrary subdomains, instead of trying to shoe-horn it
into this unnecessary heirarchical organization you just do a simple
flat mapping of subdomains to directories, like so:

server {
listen 80;
server_name ~^(.*)\.mydomain.tld$;
root /var/www/mydomain.tld/$1/public;
}

If you do it in the manner you can support arbitrary length
subdomains. For example...

sub.mydomain.tld -> /var/www/mydomain.tld/sub/public
a.b.mydomain.tld -> /var/www/mydomain.tld/a.b/public
i.complicate.configs.mydomain.tld ->
/var/www/mydomain.tld/i.complicate.configs/public

Essentially, there is no reason to think of the dot separator in
domain names as equivalent to a directory hierarchy other than that it
is comfortable.
