Hi Daniel,
Are you trying to get a summary on what kind of data residing in a feature class?
Or you want a quick visual look at the data?
If it is the latter, you can always use the preview tab in ArcCatalog, and it will show you the data as points, polyline or polygon based on the geometry type of the feature class and in addition it gives an option to check out the attribute data as well.
If you are using ArcGIS Pro, then you can do the same from within your project , by adding the Catalog View from View Tab.
