ドキュメントで気づいたように、これは機能します：
$ SCRIPT_NAME=/php_status SCRIPT_FILENAME=/php_status QUERY_STRING= REQUEST_METHOD=GET cgi-fcgi -bind -connect /var/run/php-fpm/php-fpm.sock

問題は、プロセスの再起動と、しばらくしてからの pid の「変更」だと思います。
supervisor failed to find php-fpm bin path, last attempt: "ls -la /proc/24400/exe" failed due to AmplifySubprocessError
確かではありませんが、おそらくpm.max_requests = 500責任があります。
