Target Content without Audiences

Hi all, content targeting has traditionally been done via audiences. Audience Compilation in SharePoint Online is done once a week, frm my understanding which is not acceptable for most organistions.

Looking for advice on a good way to target content without the need to rely on audiences. Keeping in mind that a user may be a member of a number of different "audiences". 

Is populating a custom SharePoint User Profile Property a viable solution? For example for every user get the groups that user is a member of, then populate a SharePoint User Profile Property with those values and have a site column with these groups as options (Terms or Choice Field) then use CSWP to display relevant content.??..??
