NanoPi R4S - NanoPi R4S rk3399 4G is a great new OpenWrt device
I host my ubiquiti docker from it and it handles my routing. I have a switch for my Lan connections and a AC-Lite for my wifi. (edit - I ideally want a POE Ubiquiti switch in future but a basic one does for now. Damn supply chain issues. Also a decent switch is far better for managing VLANS)
It is snapshot or use https://github.com/anaelorlinski/OpenWrt-NanoPi-R2S-R4S-Builds as it is not in release builds yet (It just missed out on 21.02) Oh and get the 4gb version as OpenWrt only supports that as the upstream patches from FriendlyArm havent been pushed to uboot yet. The 1gb version uses ddr3 not ddr4.
