I've found very useful the videos from u/DmLambert https://www.youtube.com/c/ZabbixCookBook/videos

Even the old ones helped to understand different concepts and issues that could appear in the long run.

Also books like zabbix-5-it-infrastructure-monitoring-cookbook are very useful (I don't know if the zabbix 6 version is out yet)
