About 40% of my flying is above FL180. I usually just file direct from the
end of the DP to point along the approach, or perhaps a point from which I
believe the approach will begin. Thus far I have never been give a
clearance with a jet airway. However, I file /G and I am based on the West
Coast. People that I know in the NE seem to get jet airways in their
clearance. However, they very seldom fly the airway that far. They are
usually cleared direct early in the procedure.

As far as filing goes, the people I know in the NE will file the jet airway
to the nearest point to the expected approach or as close as they can, and
then file either direct or Victor airway from that point to the destination,
or a waypoint near the destination.

I've never flown a jet airway (and probably never will, except on an
airliner), but here's a question. There are fewer J routes than V, and
they connect fewer navaids. So it can happen that your destination is
quite far from the nearest high-altitude navaid or interaction. Do you
still file direct from the closest high-alt waypoint, go direct to a
nearby navaid, or use low-altitude routes for your arrival?
