The same as everywhere else.

So, I take it that this means that all the userspace programs, ports,
packages, utilities, etc. do *not* take advantage of the 64-bit
extensions. That is, only the kernel gets the benefit of the
wider word. Is that correct?
No, everything is 100% native.

OK, these may be really stupid questions but:
1) How does make world know whether to build 32-bit or 64-bit binaries?
2) Can a binary from a 32-bit FreeBSD system be run unmodified on the
64-bit system?
3) If I reboot with 32-bit or 64-bit kernels, does the system magically
somehow make the userland stuff work natively at the word width?
If so, how?
TIA,
I take this to mean you have an i386 install and want to compile amd64 on
it.
