Well, no help for you, but it might be worth noting that
FreeBSD-12.1-RELEASE-amd64-disc1.iso is actually 867(!) MB, and that says:


    This contains the base FreeBSD operating system. It also supports
    booting into a "livefs" based rescue mode. There are no pre-built

    Additionally, this can be written to an USB memory stick (flash
    drive) for the amd64 architecture and used to do an install on
    machines capable of booting off USB drives. It also supports
    booting into a "livefs" based rescue mode. There are no pre-built

I.e. a) it is only the base system, no packages that can be removed
(though there are sources and other stuff that *could* be) - and b)
there is *no* claim that it can actually be burnt to a CD!!!

*Perhaps* you could mount the image via md(4), remove/truncate some of
the files in /usr/freebsd-dist, and burn a CD from the result.


PS From FreeBSD-12.1-RELEASE-amd64-memstick.img:

$ ls -s /mnt/usr/freebsd-dist
total 548264
     4 MANIFEST          76640 kernel-dbg.txz    38592 ports.txz
