I would interpret this to read that if I have a decent VOR
signal on the ground at an airport (without a designated
checkpoint) - which I do at my home airport - then a simple
cross-check is OK for 91.171.

Yep. We do this all the time. We have lots of helicopter
bases, not close to an airport, & the VOR's have to be checked
every 30 days, so we just tune in a VOR on both and cross-check
them. If we can't get a signal on the ground, a check in the
air will work.
