Is there a shortcut or one or two areas to look at to check a CU's health?

The NCUA call reports clearly disclose the total of insured and the total of uninsured deposits for a given institution. This allows you to compute the percentage uninsured deposits are within the overall total. You want that percentage to be as small as possible. Too large a percentage of uninsured deposits can precipitate, under exigent circumstances, a run on the credit union, thereby enhancing likelihood of collapse.
Opinions on this will vary. But my personal yardstick calls for uninsured deposits to be no more than 10% of the total, else I commence worrying.
