The WAN interface is configured as the default route. There are other purposes and uses for this configuration, but it is safe to say Internet Access is the most common goal. DNS and DHCP are typically running on a server; why is it not a good idea to run these services on a router?
This is for the clients that get a DHCP address from that network. This is what the USG will use to look up Names. I think the WAN > Preferred/Alternate DNS can be set for all UniFi devices so they can bypass the DNS servers listed in the Networks > DHCP Name Server.

Having this means that your router can easily ...
Key Differences Between DNS and DHCP. DNS is used for resolving and recursively resolving the address to name or name to address of the host. On the other hand, DHCP is used for allocating the addresses to the host in the network dynamically or statically. DNS uses port number 53 whereas DHCP could either use 67 or 68.
The WAN interface is most likely a routed interface as opposed to a switched interface. The WAN interface is expecting an ethernet, layer-3 handoff. The interface is configured to accept a DHCP address (a static address can usually be set). The WAN interface is configured as an "Outside" interface in respect to Network Address Port Translation ...
WAN DNS is what the router will use, while DHCP DNS is what your devices are told to use. Generally if you want to change DNS provider it's best to change the WAN side and leave DHCP pointing at the router so any internal name still work. If however, you want to run pi-hole or something like that then you'll have to set that in DHCP.
The DHCP (Dynamic Host Configuration Protocol) and DNS (Domain Name System) are created to make it easy for us to use networks or the Internet. They are not competitor, but work with IP addresses in a different way.

I use Coudflare's 2 DNS ips on the WAN DNS in the USG. Both my pi-holes are pointed at my USG. DNS requests look like this. USG DHCP/DNS-->Client>Pihole>USG>Cloudflare. This allows me to log client access to pi-hole to narrow down false positives or issues and change my WAN DNS to anything I want in one place without having to DHCP refresh clients.
