My impression is that this might not exist yet (the currently available projects are significant lacking in either features or reliability), and that my odds of getting something user-friendly with tools like pfBlockerNG are even slimmer.
I always feel so handicapped when something breaks on my router, due to being so much less familiar with BSD, and due to it being an older / limited FreeBSD release (many things missing from the pf repos).
Just last week my pfsense upgrade resulted in a non-booting system, and I felt helpless (user error -- zpool upgrade but didn't upgrade something about the boot directory). I didn't have my usual tools, so I ended up having to install ZFS support to an old RPi3 running NixOS just so I could look around and get the ZFS parts sorted and figure out what happened. (Thankfully I eventually found an old mailing list thread with some obscure incantation that I ran from a pfsense installer usb and resurrected things.)
The whole time I just really wished that I could have been on a Linux machine with my familiar GNU tools!
