WAN interface
There is no such thing as traffic going to a LAN address
an undocumented shortcoming, the firewall cannot understand traffic going to an internal address. Instead the traffic goes to the public WAN IP
you can't apply firewall rules on the WAN: they don't work

Some websites like digitalocean for example is actually behind cloudflares reverse proxy. If you have any website like this on your alias and it resolves cloudflares proxy IP. If these proxy IPs end up being blocked half of the internet will be broken for you. Plenty of sites use CDNs or have backend resources proxied by cloudflare. DNS based blockers are far better for your needs.
The pfBlockerNG package (pfBlocker-NG Package) offers mechanisms which can be useful in this area, such as DNSBL, geographic IP address blocking, and automation of AS lookups.
Selectively enforcing pfBlockerNG for specific clients or networks: filtering content for specific clients or networks in pfSense while keeping pfBlockerNG is not a simple task. If we wanted a simpler solution, we could’ve just added a Custom DNS server for our VLAN we wanted content filtered on. Unfortunately, doing this circumvents Unbound (DNS Resolver) and we lose the functionality of pfBlockerNG. To complicate matters more, Unbound does not allow you to specify different servers for the same lookup zone based on who’s querying the server.

Block Malicious IPs in pfSense at David's Homelab

define a rule on LAN to allow a workstation to pass traffic to destination- the firewall itself. This allows DNS queries to go between the workstation and firewall when the firewall is the DNS server ubound.
