Respectfully the scenario you want to present seems to change. The title you submitted this under doesn’t have any mention of switching, firewalls, dhcp server or WiFi access point.
Then the actual title of the article mentions routing and switching but not a firewall, dhcp server or WiFi access point. Then at the end you seem to change the goal to being a WiFi router but really you have presented more steps than required for that. You have also setup switching, a firewall and a dhcp server which are not required to be a router with WiFi access point.

Man that is totally a fair point.
I feel like I’ve struggled with the tutorials on these configs so many times in my life that I’ve kind of munged several ideas together here. There’s so much subtlety to the iptables/nftables rules that I failed to understand for so long, that I forgot that some folks might not understand that WiFi has specific weirdness. You’re right- I open with routing as a topic, but I’m in a very specific nuance right away.
