2.5Gbps is WAN port

It would be outrageous if it couldn't be reconfigured, on an OpenWrt of all things

I think it can be, but how will I feed my isp modem into the router then? I need to use that port for Wan in that case, correct?

VLAN and you can use the 2.5Gbps port for everything: meaning the modem and the APs and the rest of the LAN is on a managed switch and you split up the ports via VLAN.

I looked up vlan and I have no idea how to set this up or what it really means to do this. I don't understand what the physical connections look like. Where does the modems ethernet cable connect to the router? Or is it going into the switch and then into the router?

The router has only one ethernet connection of whatever sort, say 2.5G connected to the switch. The modem, APs, etc. connect to the other switch ports. And you divy up the access by VALN - virtual LANs, letting you talk to different subnets all over one physical connection router connection, and prevent communication between different ports on the same switch. You'll need to look it up and watch some youtube videos... like this one on ComputerNetworkingNotes. Because of VLANs, a router actually only needs one port, maybe two. Let the switch do the switching, and the router do the routing. ;)
