Right. An extended partition is something MS came up with to get around
some historical narrow thinking. FreeBSD doesn't need that.
It just needs slices (which are called partitions by Microsloth).

Well, it really all is just label stuff. I don't know if I would
strictly call it cosmetic.

If you let fdisk turn the space in to a FreeBSD slice, then it is a slice.
If it is a slice then you can install FreeBSD on it (providing it is
big enough). You will need to let it install the boot manager to
be able to dual boot.
