I think you are better off only using 1 LAN connection which could be a lagg connection out of a firewall. I think it is better design. The only data I want on my firewall leg is internet traffic. All local network traffic stays in my local network. Even with layer 2 traffic I think it is a better design.
I use multiple APs connected to my switch. I use 2 SSIDs on each and every AP. Each SSID is a separate VLAN. I use 1 SSID for guest. Each SSID has both 2.4 and 5 GHz defined to them. So, every AP has the same set up on it. As you move out of range of 5GHz then it will automatically switch to 2.4GHz. I have another AP waiting to be installed in my wife's sewing room. This will keep her on high speed 5 GHz as she has 2 walls for the signals to pass through right now.
I have a third Cisco CBW150ax AP waiting for my granddaughter to show up so she can help me install it. I want her to see how it is done. She is going to spend the summer with us. I already had my granddaughter redo under my supervision set up my core network using a large APC UPS. I made her redo all the cables and make them neat. She likes doing it. There are 7 devices in my core. She made the batteries hot in the APC. I was hands off; she was my hands. I just straw bossed.
My old Cisco APs had 2.5 gig ports but I decided it would be better to have more APs than fewer APs. And I have already moved to a 10 gig card in my pfsense router/firewall. I don't see me dropping down to 2.5gig. I am not happy with my 10 gig switch as it is still a little noisy.
My final plan which I have posted years ago would be to run a routing protocol between my router and my L3 switch. That way the router will pick up all the networks automatically from the switch through the routing protocol. So, I would like the connection between router and L3 switch to be a little larger than my internet bandwidth to account for router protocol overhead. In a small home network, it would not be very much but in larger networks it can chew up 10% or more of connection bandwidth.
The last is just me rambling.
