First thank you both for respomding.  After reading your responses and reading some more about lagg and lacp, I think this may work.  What do you (anyone) think?

Optiplex 5050 with OPNsense
     Static Lagg - Lagg 0
          inc0
          inc01
     Static Lagg - Lagg 1
          inc02
          inc03
     Interface em1 --> WAN ISP 1GbE

:Netgear GS724T V2
     Static Lagg - Lagg0
          Port 22
          Port 24
     Static Lagg - Lagg1
          Port 18
          Port 20
     Static Lagg - Lagg2
          Port 21
          Port 23

Netgear JGS516PE
     Static Lagg - Lagg0
         Port 15
         Port 16

Optiplex Lagg0 --> GS724T Lagg0 - Vlan1 (default)
Optiplex Lagg1 --> GS724T Lagg1 - Vlan (1,10,20,30,40,50,60)
Gs724T Lagg2 --> JGS516 Lagg0 - Vlan (1,10,40,60)

In regards to cabling each Lagg member port would be cabled 1:1 to its corresponding lagg port.

The GS724T is LACP capable but the JGS516 PE is not.

Appreciate any feedback.

First I have been a pfSense user and am setting up to move to OPNsense.  Purchased a used Optiplex 5050 (I5-6500, 32GB Ram, Intel I350 4 port 1GbE NIC, Intel I219-V 1 port 1GbE NIC, 256GB M2 Sata Drive).  I have successfully loaded OPNsense 23.7.8_1 on it and beginning configuration.

I have set up 1 of the I350 ports as the WAN interface and another as the LAN interface.  So I have two free ports on this NIC and then the 1 built-in port on the other NIC.

I have two Netgear managed L2 switches that are both 802.1Q VLAN capable and LAGG capable.  I have setup VLAN's but never setup LAGG.  I will have (7) VLAN's including the default plus Wireguard.

My thought is to move the WAN interface to the I219-V port, then LAGG (2) of the I350 ports together for LAN and using LAN for only OPNsense and the switches (Default VLAN 1), then bonding the other two I350 ports together for the other 6 VLAN's.  I have plenty of room (ports) on my switches for this configuration.

Is this feasible?  What might the pitfalls be?  Any and all opinions/guidance would be greatly appreciated.
