I think you're right -- FreeBSD amd64 defaults to 9600 according to
boot(8), but arm64 has 115200 compiled, in device tree?

Fwiw I typically set "-Dh -S<speed>" in /boot.config on PC's, but now
I'm realizing that may be ignored by arm platforms?

In theory serial speed can be set in config.txt (e.g. init_uart_baud)
but that may be a linux-ism, I don't know if FreeBSD will use it.

I was admittedly focusing on FreeBSD loader config rather than Pi
settings, though; maybe it can be set in /boot/loader.conf if needed,
e.g. comconsole_speed?
