My approach would be to go for 3 slices. Slice 1 would be a suitable size to
hold the OS and swap, I have quite a lot of ports installed on my desktop PC
so would go for about 20 to 30 GB. This could be less for a server but with
1TB you can afford to be generous. This can then be partitioned to suit with
whatever combinations of /, /usr, /usr/local, /var. /tmp and swap suits your
The second slice would be the same size as the first and be left empty for now
as a spare.
The third slice, the rest of the disk, would be for all of your data and could
be partitioned (or not) to suit your needs for /home and any other local data
requirements. If there's to be any large mysql databases then I'd put them
here with symlinks from /var where mysql normally expects to find them.
When you come to upgrade to the next FreeBSD release just install it into the
spare second slice and boot from that instead of the first. If you experience
any serious problems with the upgrade then nothing has been lost and you can
just revert to booting of the first slice until things are sorted out.
The above is all assuming you're using UFS. If you're going to use ZFS then
there are other possibilities like using sysutils/beadm from ports

environments in a single partition.
