I thought about it, but WiFi cards are generally better supported on Linux, and since I'll be running OpenWrt on the APs, I'd prefer having a unified OS for both APs and the router.
I guess it will depend on how much I like OpenWrt :) I don't have any experience with it.
If you do go the OPNSense route, just be aware you need to disable the spectre/meltdown mitigations to get reasonable performance. pfsense has them disabled by default.
