The default date format is US (and almost everyone else uses the international DD/MM/YYYY format).

How do I change the system default, so that the date in PCManFM, for example, shows in the international format?

(I found Clock settings but that only affects the panel clock.)

Arrange your startup so LANG (or at least LC_TIME) is set in time for whatever launches PCManFM to pick it up.

Typically you put export LANG= in .bashrc, and then if you have a login shell somewhere in your startup sequence, it gets set.
You can do this by having the display manager launch /bin/bash -l -c /usr/bin/lxsession
