256 MiB might be good for root-on-UFS with a _minimal_ installation using legacy files (not packages).

For a non-minimal installation, I'd allow more memory.
files are ok too, if you just install it elsewhere. doesn't matter if it's big machine, embedded, vm. i mainly imagine this is sbc which actually needs this
i heard efi loader can't do <256m but
but
i recently did tests (with installer)
those (a copy):
14.3:
95m - still boots multiuser
94m - kernel won't boot (load fully?)
89m - loader can't load kernel at all
65m - loader won't load
panic: Could not malloc 163840 bytes with M_WAITOK from /usr/src/sys/contrib/ope
nzfs/module/zstd/zfs_zstd.c line 788
2m - "loader loader" won't load, just spins a bar a bit
1m - same
<1m - nothing boots (really a 64bit machine with less than 1m ram?)
tests performed by:
qemu-system-x86
_64 -m x -display curses -k sv -rtc base=localtime -drive file=FreeBSD-14.3-RELEASE
-amd64-memstick-custom.img,format=raw,discard=unmap,detect-zeroes=unmap
