I know there is some limitation for the AEM OOTB assets reports generator but you can use the ACS commons report generator tool by specifying queries as per your requirement.
There is an OOTB asset view servlet http://localhost:4502/bin/wcm/contentfinder/asset/view.json/content/dam/
This gives a list of all assets along with some metadata information. See this https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/aem-generate-asset-report-...
If you want to get a list of assets with a specific tag, you can try using the query builder,
The code below finds all dam:Assets with a specific tagged:
type=dam:Assets path=/content/dam/ tagsearch=AEM_TAG_HERE
