Comment (by Veence):

 I have just committed a patch and submitted it upstream to fix the wrong
 relative rpaths in QGIS server's providers. This is fixed, and ideally
 this patch should be integrated into future releases. I have not
 investigated why we end up with a wrong QGIS_PREFIX_PATH value in QGIS
 server that subsequently blocks the loading of the various plug-ins and
 providers, whereby the server doesn’t work properly. I have also reported
 that upstream.

 However, there is an easy workaround: just set the environment variable
 QGIS_PREFIX_PATH to "/Applications/MacPorts/Qgis3.app/Contents/MacOS".
 Exemple with lighttpd:

 {{{
 fastcgi.server = ( "/wfs" =>
                     ( "wfs" =>
                         (   "socket" => var.socket_dir + "wfs.socket",
                             "bin-path" =>
 "/Applications/MacPorts/Qgis3.app/Contents/MacOS/fcgi-
 bin/qgis_mapserv.fcgi",
                             "bin-environment" => (
                                 "QGIS_PREFIX_PATH" =>
 "/Applications/MacPorts/Qgis3.app/Contents/MacOS",
                    […]
 }}}

 With that, the server works:

 {{{

 }}}

 I might commit a further patch when I have identified the problem with the
 wrong default QGIS_PREFIX_PATH, but meanwhile this is a satisfactory
 workaround, I thus close the ticket.
