"In" or "from"? If they are in the ports tree but not installed,
don't mind. If they are installed, deinstall them as recommended,
using pkg_delete for example.

Very well you mentioned this - this difference between "base OS"
and "installable packages" is one of the most important features
of FreeBSD to me.
Having said this, all the additional software (from ports or from
packages) reside within /usr/local; everything outside /usr/local
belongs to the OS.
This means you can
# rm -rf /usr/local
# mtree -f /etc/mtree/BSD.local.dist
and then start installing the software you want. The base system
won't be affected at all.
# cd /usr/ports/<category>/<port>
# make install package clean
# pkg_add -r <what you want>
So you end up only with the things you intendedly install (including
the needed dependencies).
This is the way I did setup a 5.X system many years ago which died
this month due to a problem killing various inodes... :-(

You can, of course, just deinstall the packages you know you won't
need, but as you said, if there are more than 250 of them installed
(related to X, maybe Gnome or KDE, too), it's easier to invest some
time and build from scratch, just as you need.

See? Everything there from the base install. :-)
