What's a typical value for battery current drain when a vehicle is
totally shut down, no lights on, etc. ??

What are your experiences? Suggestions. If .19A is obviously high,
where might I start looking?

I've just checked my Peugeot 306 and with only the clock running, the
current is 6 mA. 190 mA sounds very high.

Mind you, I once left my car door ajar over night so the courtesy light was
on for about 10 hours, and the car still started perfectly in the morning
after a drain of maybe 5 Ah (6W, 12V so 0.5A, for 10 hours).

You might have a combination of higher than normal current drain and battery
that isn't holding its charge as well as it should.

Checking for current "leaks" may require you to pull out fuses one by one
and see which one reduces the current flow. I'm not sure what the best
precautions are for preventing damage to sensitive electronics - maybe
disconnect the battery, remove another fuse, reconnect battery, measure
current, repeat ad nauseam.

Pulling fuses one by one is a good method. However, no good would be
done by disconnenting the battery each time. That would not increase
protection for any electronics, and it actually would switch standby
electronics many times instead of just once.

If you have one, use a non-conductive fuse puller tool rather than a
metal tool, to avoid an accidental short on the terminals.
