Also watch out for the constituent member ( volumes under the covers ) count - I find the "default" is too high sometimes for the solution I am looking for.

Yes, it helps. Especially for HFC environments, it definitely helps (High
file count). Even if the FlexGroup is only on one (1) node, it makes a
difference and it can be quite big, it depends on the workload pattern.
BTW it's not really advisable to span a FG across more than four (4) nodes
over the ClusterNet switches, even if you have a large cluster with >16 nodes
