In ArcMap, when adding a field, the options presented are Short Integer and Long Integer. In Pro, they are Short and Long. This is fine if you know what they are, but if you're learning GIS or forgot, including the word "integer" is a helpful reminder; I see no reason to take it away.
This also would mirror the online help documentation, which does include the word 'integer.' https://pro.arcgis.com/en/pro-app/latest/help/data/geodatabases/overview/arcgis-field-data-types.htm
