I would like to see Field Config Cardinality support EntityReferenceBrowserWidget as well. It would require some refactoring of the Entity Browser widget too (if we do not want to repeat a lot of code). I brought this to Entity Browser as feature request: ✨ Entity Browser Entity Reference Widget: wrap getCardinality() in own function Needs review .
Use entity browser widget together with Field Config Cardinality. Entity browser widget does not respect Field Config Cardinality settings.
Extend EntityReferenceBrowserWidget similar how it was done for MediaLibraryWidget in #3117908: Cardinality for MediaLibraryWidget →
Entity Browser widget will respect Field Config Cardinality setting (e. g. messages for remaining and total allowed elements, radio vs checkbox etc.)

It's likely this issue predates Contrib.social: some issue and comment data are missing.
None of the patches do apply against latest dev anymore.
@0livier: Thanks for the improvement suggestions, they make sense.
Not sure at this moment why I had this rather difficult return statement, but I think there was some edge cases to consider. So I did not use your simplified statement here. Feel free to change or explain.
Providing patch based on #4 with suggestions from #5 that applies to latest dev, hopefully.
