I'm not much of a WP guy, mostly Drupal ;), but I think that this WP

You need to install the cache purge 3rd party module:

Note that this is a route that voids solutions like SuperCache. It's
more complex to setup, but ultimately much more flexible.

Since you're already using Nginx as a reverse proxy is a "natural"

No need to use Varnish.
