opnsense on Proxmox, replacing Unifi UDR as primary router, is this NIC bridge config right?

I'm replacing my broken Unifi UDR with a N100 fanless box running Proxmox 8.2.2 and OPNsense 24.1.

The N100 box has 4x dedicated Intel 226 NICs and 1x Console port.

I have a ADSL2+ modem connected to eth0 as WAN (my internet is 80MbpsDown/16Mbpsup, but planning on getting 1G up/down fibre in the next 2-3 months). In Proxmox I've created a Bridge at the host level and added the three remaining eth1-3 (ensp1s0-ensp3s0 interfaces). So that Proxmox is effectively creating 1x interfaces that acts more like a switch.

OPNsense will then treat anything plugged into eth1-3 on the physical computer as being part of the same network and will issue them IPs from the DHCP. I have 2x UniFi APs that I need to plug into the N100 box and an additional wired Proxmox server running HomeAssistant and other services.

Is this config right? I'm new to running OPNsense as a virtualised device on Proxmox. My plan is to also run the Unifi Controller and later, a Pi-Hole instance on the same N100 / Proxmox Host. I'm also going to expand to get a PoE switch in about 1-2 months time. Which I'll be plugging the Unifi APs and sever into.

Also, is there a way to be able to use / incorporate the Console port, either into OPNsense or as a backup to be able to get to the Proxmox WebGUI? It looks like the connection is an RJ45.
