Check out teklager, I suspect they have the best option for you but my research on this was done about 2 years ago so you might want to have a look around. There's cheaper options that come from China but I am paranoid about back doors.

I've been running an old Netgear R7800, as an all-in-one plastic OpenWrt router+switch+WiFi.

It's been so solid, that I haven't bothered to move to the Netgear RAX120v2 that I bought as an OpenWrt upgrade. (It tested fine with OpenWrt 24-rc, then I put it in storage for a more pressing occasion to upgrade.)

I also got a Netgear WAX220 WiFi AP, which I put OpenWrt 24-rc on, and tested with an OPNsense box (since OPNsense isn't good for WiFi). I decided I preferred OpenWrt for my simple needs for the router, but it's a nice enough OpenWRT WiFi AP that I expect to need it again someday, maybe to hang off a beefy OpenWrt PC-based router that's running IDS/IPS or something.

I went searching the OpenWRT forums and wiki for recommendations and ended up with the GL.iNet MT-6000. The stock firmware is a gui around a modern OpenWRT and they don’t try to lock it down at all so flashing is easy.

Seconded. The MT-6000 is basically the gold standard for OpenWRT at this point in time.

Thanks, I ended up going with this one. Looks like there's a new Flint 3 coming, but rumors seem to be indicating it is going to be more expensive and is possibly not OpenWRT compatible due to chipset. So, Flint 2 it is for now.

I recommend a Dynalink AX3600. Really fast CPU, tons of RAM, great WiFi, and works perfectly with OpenWrt. $59 on Amazon.

Take a look at OpenWRT One.

I'm happy with OpenWRT on a NanoPi R4S, but that doesn't have wifi built in.

Probably won't apply to you but for rackmount I have a Gigabyte GA-IMB410TN + Pentium Gold G6405, in a 1U Logic Case SC-1280, with a quad-port 2.5 GbE Realtek PCIe NIC (r8125) to supplement the motherboard's dual 1 GbE Intel NICs (igb & e1000e).

The motherboard can run off of 12-19V DC input via 5.5mm barrel jack (e.g. any old unused high-power laptop charger), or 12V via a 4-pin CPU EPS power connector (they are commoned together). Since the case comes with a 250W 1U Flex ATX power supply, I'm doing the latter.

This lets me take the PSU's 12V rail out via the barrel jack (edit: with 18 AWG cable, I know) to power the modem and a couple of TP-Link 2.5 GbE network switches which all run on 12V, saving 3 wall warts. Both switches are velcroed to the top lid with 20cm patch cords for 2.5 GbE ports 1 and 4. I have 5 LANs at home, so the 6x wired ethernet ports this gives me are perfect.

OpenWRT runs pretty great on amd64 and I've been running the v24.10 branch (pre-release) for several months on it without issue.
