yes, although I believe this points more into a detailed view on settlement
shape, like "Straßenangerdorf", "Streusiedlung", "Ringdorf", etc. i.e
.typological classes of settlements according to their development and
shape / spatial organization.

whether a single farm is a kind of settlement (so called "Einzelsiedlung")
is a question of definition or theory, it doesn't really matter for us, in
OSM it makes sense to provide a place value for them.

I wouldn't include fields, at least not those that are on the "outside" of
the settlement, while those enclosed by buildings typically could be
included. You'd likely have to decide on a case by case basis, where
context (like the above mentioned settlement typologies matter). In the
case of sparse settlements, finding an outline might be hard or impossible,
but fortunately in the areas I map, this is almost never an issue ;-)

PS:
For more examples, have a look here:
https://de.wikipedia.org/wiki/Kategorie:Dorfform
and here: https://de.wikipedia.org/wiki/Kategorie:Stadtform (particularly
in the case of cities, these are often idealized concepts, and in reality
you will find mixed forms, because the ideals changed before "completion"
of the original plan, or because they have been transformed later to
compensate for problems they didn't foresee and/or to "modernize" the city,
still those concepts typically can still be seen).

One famous example for an idealized city shape where you can perfectly
observe the original plan is Karlsruhe, a city founded 300 years ago as
planned community (baroque style):
