Microsoft Search returns all SharePoint sites that a user has access too, however, many of these sites are now the backend of thriving Microsoft Teams sites. Having users find and land on the SharePoint home page in these cases is not useful.

Two possible improvements. Either, make the link to the public Teams sites show up as along side the SharePoint results (with some icon to distinguish the two), or put a prominent link to the Teams site on the home page of the SharePoint site.
