I think you are wondering if you should "fastcgi_pass php-fpm-service"
instead of "proxy_pass this-wb-service", and I suspect the answer is

In nginx, you fastcgi_pass to a service and set some fastcgi_param
values that your fastcgi server cares about. In the "common" case,
that is based on the incoming request details and suitable variables
are already populated.

In this case, that may or may not happen, so you may need to set things
like SCRIPT_FILENAME manually -- I have not tested to see what is needed.

I don't understand what you mean there. The config you showed previously
had no "localhost" that I could see.

Possibly it does not matter now.
