The scripts you linked are for the broker's "home" directory. This is different from the scripts used to start an actual instance of the broker (which I previously linked). The home/instance model is described in the documentation [1]. I just removed UseParallelGC from those scripts [2] to (hopefully) avoid this same confusion in the future.
I think the counter issue you're observing is almost certainly unrelated to your use of ZGC. I think you're safe to use ZGC.
