I have absolutely no idea how "fi" magically got poked into the debconf
database.

If you didn't see any debconf questions about the X server until you ran
dpkg-reconfigure, then this must be what happened.

The xserver-xfree86 configure script has no logic for automatically
populating the keyboard variant parameter.  It always defaults to blank[1].

My *only* guess is that language-chooser or some similar mechanism in d-i
stuffed this bogus value into the debconf database.

I am CCing debian-boot to see if they find that to be a plausible
explanation.

If they don't, then I have no clue how your debconf database got corrupted
in this fashion.  It sounds like pure magic.

[1] Here's the code, if you're interested:

/var/lib/dpkg/info/xserver-xfree86.config:
   1644 MAY_BE_NULL=yes validate_string_db_input "$(priority_ceil $PRIORITY)" xserver-xfree86/config/inputdevice/keyboard/variant

(Yup, just that one line.)

/usr/bin/dexconf:
    230 ### KEYBOARD / INPUTDEVICE
