Other choices I considered were writing to a raw socket but it would be a lot

Why are you concerned about fragmentation?
Provided you don't set INP_HDRINCL then the kernel will include relevant IP
headers and handle fragmentation for you (at least that's my understanding
looking at NetBSD's code).
The only extra overhead you should have is writing the UDP header which is
pretty straight forward.
