Telemetry based analytics

As a PO, I would like to have telemetry inside the BeaconCMS for the internal use. Events used for buttons, links, etc. must be helpful in case of analytics and product management to make future decisions. We have to research potential candidates here or create our own solution (preferable). If we'll go with own solution, we have to choose temporary one, before our own telemetry will be implemented. We can check as a potential candidates: Plausible, Superset?
