Can't figure out Nginx PHP

I’ve been scouring through all the nginx, Wordpress, PHP threads but I can’t seem to get what I need. I have a Ghost blog installed (working fine) and am trying to add a Wordpress along side it. The Wordpress block looks like:

server {                                                     
        listen 80;                                           
        listen [::]:80;                                      
                                                             
        root /var/www/html;                                  
        index index.php index.html index.htm;                
                                                             
        server_name wpdomain.com;                        
                                                             
        location / {                                         
                try_files $uri $uri/ /index.php?q=$uri&$args;
        }                                                    
                                                             
        error_page 404 /404.html;                            
        error_page 500 502 503 504 /50x.html;                
                                                             
        location = /50x.html {                               
                root /usr/share/nginx/html;                  
        }                                                    
                                                             
        location ~ \.php$ {                                  
                try_files $uri =404;                         
                fastcgi_split_path_info ^(.+\.php)(/.+)$;    
                fastcgi_pass 127.0.0.1:9000;                 
                fastcgi_index index.php;                   
                include fastcgi_params;                      
        }                                                    
                                                             
}                                                            

I’ve tried the alternative:

fastcgi_pass unix:/run/php/php7.2-fpm.sock;

with the appropriate listen adjustment to no avail.

The status looks fine:

php7.2-fpm.service - The PHP 7.2 FastCGI Process Manager
   Loaded: loaded (/lib/systemd/system/php7.2-fpm.service; enabled; vendor preset: enabled)
   Active: active (running) since Thu 2018-02-22 00:22:56 UTC; 6min ago
     Docs: man:php-fpm7.2(8)

   Status: "Processes active: 0, idle: 2, Requests: 6, slow: 0, Traffic: 0req/sec"

           ├─22066 php-fpm: pool www
           └─22067 php-fpm: pool www

and I can access the non-php files just fine, but I can’t setup Wordpress until I can actually access the PHP. I’m not seeing errors in /var/log/nginx/error.log either, I’m not sure what else to check at this point…
