As far as my GUI stuff in general, I use
x11-wm/fvwm2 and my config calls for
x11-themes/cursor-dmz-theme,
x11-fonts/terminus-font, and
x11-fonts/artwiz-aleczapka. The dmz-theme also needs
ln -s watch dot.
The standard X stuff I use a lot is basically
xterm,
xclock, and
xmessage, all configured a bit with xresources. While I don't have them installed and they may not even all be available on FreeBSD (though I assume they are) I usually have
gxmessage,
xdialog,
gtkdialog, and
yad as additional 'script widget doohickeys'. I think I've gotten almost all scripts off gtkdialog but they actually are all different (except xmessage/gxmessage practically speaking) and are all better suited for one thing than another. Another thing that isn't part of X and isn't a scripting widget but is another X doohickey is the invaluable
x11/xclip.
I use
www/dillo2 and
palemoon for browsing (though I've installed and may switch to
www/librewolf because it plays youtube without pulseaudio).
I use
graphics/geeqie and
multimedia/mpv for graphics and video (and audio), and
graphics/mtpaint for my minimal graphic-editing needs. Oh, and also
graphics/feh because it's the best background setter I know and also an interesting image viewer. Also mainly
print/qpdfview for a pdf viewer, though I also use
graphics/zathura and its plugins for various document viewing.
xpdf has improved in ways lately, but has more deps and I haven't installed it.
For my big gaming, I use
games/sol which is the most 'just a deck of cards I don't have to shuffle' version I've seen.
There are more programs related to document viewing that I haven't installed yet and may do without like
kchmviewer for epubs and
djview for djvu.
Other apps I'm doing without right now are
gkrellm and
root-tail (aiming for a quieter desktop and not spending resources monitoring resources.

)
Otherwise it's basically cli and a lot of tui - if I can run it in tmux I generally do. But I'll be following this thread closely because, other than fvwm and its closely related stuff, and maybe stuff I don't care much about like graphics editing and sol, I may like a lot of this GUI stuff but I'm not
completely satisfied with it. Especially not with all the things that dragged in avahi, dbus, polkit, et al.
