Answer 1

if i have understood what you meant by flat buffer on polygon, you could apply these steps :

• feature to polyline.
• Split at vertices
• buffer with flat enabled
• Append the original polygon to the buffer_result
• dissolve on a commun value, if there's not a commun value, add a field to make commun value
