WRT3200ACM is what I use. It's one of the most powerful consumer devices with wifi supported by openwrt. It's powerful enough for a router with a little firewalling, VPN (wireguard only if you want speed), DoH and some Ad Filtering but thats pushing it's limits from my experience. If you want more power https://openbsdrouterguide.net/ is your friend.
That being said there is no hardcore prosumer hardware out there for this purpose. The moment you go beyond home user router hardware like the WRT3200acm you are in either CISCO Buisness stuff or custom server builds. Potentially a Raspberry Pi 4 with a PCIE ethernet card is closest to prosumer hardware out there and there's a lot of hacking involved to get that running to the same degree as a openwrt router
This is interesting. I'm going to research it further. I really appreciate the feedback. I'm really starting to hate DoH - and I may just not put any IoT thing on my network that uses it. Maybe that's the way to go.
But I doubt most consumers really care. It's complicated.
