Hello,
Thanks for posting all of this detail. There are many moving parts when it comes to successful captive portal.
To answer your question:
Is the idea that the AP redirects web traffic to access control using the IP Firewall object? This removes the need for a core router with PBR configured. All of my network is VLAN 1 and not routed, does this matter?
That is correct. There must be SOME mechanism in the network to redirect client traffic in order for NAC to send it's captive portal. Traditionally that was a PBR in the core router to send internet bound traffic to the NAC.
Mostly today we see AP/Controller based redirection mechanisms that perform this task.

The AP/Controller will spoof the destination site and send back a redirect error code with the a new URL that is the NAC appliance. The browser will them directly contact the NAC to display the captive portal.
Thanks
