I use a Microtik hAP AC (Small little SOHO style router with an sfp and PoE). You can easily flash it with OpenWRT and use wireguard on that. All open source too.
It's great hardware but I'm no personal fan of RouterOS.
It's brilliant, everything works fine. I've even used the USB port with a smartphone for 4G backup tethering (just need to add relevant usb packages, the openwrt wiki details all this). Plus there's the luci web interface which runs like a charm. No complaints whatsoever.
