IDS IPS for pfSense

I am starting into IDS and IPS and monitoring with pfSense.

What programs/monitoring software would those with experience suggest?

Programs: snort vs. Suricata or something else?

Monitoring: Greylogs, Zabbix or something else?

Also looklng to use Fedroa Linux to run the monitoring software rather than Ubuntu so links for Fedroa Linux setup would be helpful on that side.

Either Suricata or Snort are fine, Graylog is great for logging which is important when you need to look through the details around a security incident.
