I started with this community build - Rpi4 < $(community_build). I have a Unifi Pro connected as an AP for Wifi. Been running great for 4 wks. IMO, the RPi is much more flexible and has enough power/RAM than most of the std home routers out there.
The community build has most of the typical packages built in, i.e. adblock, SQM, banip etc. But I have since learnt how to compile my own image with the packages I need using instructions from https://openwrt.org/docs/guide-user/additional-software/imagebuilder. Have fun!
