Improved Network Configuration for AP7 Optimization

I am trying to improve my AP7 speed or efficiency. Currently my network is setup as follows:

ISP 1.8 Gbps > 2.5 Gbps modem > FWGP 10G > 2.5 Gbps Omada PoE++ Managed Core Switch (24 ETH, 4 SFP+ ports )> individual home runs to (5) AP7's (three AP7D, 2 AP7C).

I want to connect each AP7 directly to a 10G capable switch. As all Wi-Fi traffic or ethernet traffic from individual AP7's via the 2.5G port, I decided to use an unmanaged 10G switch to save money. 

My proposed setup would be:

• Modem to FWGP 2.5 Gbps port
• FWGP 10G Port 4 > Unmanaged TL-SX1008 with home runs to each AP7.
• Will also connect one 10G port to my Core Omada switch SFP+ port to allow for 10G communication between the core switch and 10 G switch and FWGP.

Another option could be:

• Modem to FWGP 2.5 Gbps port (No Change).
• FWGP 10G Port 4 > Unmanaged TL-SX1008 with home runs to each AP7 (No change).
• Connect the one 10G port to my Core Omada switch SFP+ port to the second FWGP 10G port to allow for 10G communication between the core switch and the Firewalla router.

I am also thinking about lagging ports together but have not done this before.

• Lag Thoughts - lagging the two 10G FWGP ports and run one cable from each port to the 10G switch port and 2.5G switch SFP+ port. 

Traffic isolation thoughts:

• I am relying on FW AP7 VqLan utilization to monitor and manage the Wi-Fi from each AP to the router.
•  I am relying on FW AP7 VqLan utilization to monitor and manage the ethernet traffic coming into each AP7 2.5g port to the router. Typically, a laptop or remote switch connected to streaming devices or printer.

Please let me know if its a complete mistake to try and save money by purchasing an unmanaged switch installed between the AP7's backhaul path and Firewalla router.

Please let me know if you have suggestions on how to optimize the AP7 paths as 10G vs being routed thru a 2.5G switch.

Thank you
