When you publish a feature class projected with a specific Datum from ArcMap to ArcGIS Online for use in Collector for ArcGIS. I am trying to figure out the best way to get collected data points to support Datum CA8311F, but I am not finding any documentation on the datum or this workflow? Any help would be greatly appreciated!

You can set the projection of the feature class to Datum CA8311F and publish the feature class to arcgis server or arcgis online as a feature service and the service will be automatically converted to Web Mercator Auxiliary Sphere.
You can refer to the following links to get a better understanding: -
I hope this helps!
