Just setup lagg on my laptop and it was easier than I first thought. So now if I'm not on a wired connection it'll jump to WiFi. My Wifi chipset is iwlwifi0: Detected Intel(R) Wi-Fi 6 AX200 160MHz

On WiFi I get 275Mbps by 97Mbps
On wired I get 987Mbps by 94Mbps

FYI It was all in the excellent handbook here.
