The selections made under NAT/Port Forward/Edit; the rest left at pfsense default

Interface: WAN
Protocol: TCP
Destination: WAN
Destination port range: 443
Redirect target IP: 192.168.2.100

Strange, your are omitting the "Redirect target port" field.
It should be

Redirect target port : 443

en then pfSense will accept your NAT rules :
