Is it safe to use polygon in QGIS?
However, some tools do make a distinction, QGIS being one of them. If all you will ever have in a shapefile is simple one-ring shapes, then you can safely choose Polygon. If the shapes may contain “holes”, it is also safe to choose Polygon.
How are shapefile polygons constructed from closed rings?
Each Curve in the boundary of the MultiPolygon is in the boundary of exactly 1 element Polygon, and every Curve in the boundary of an element Polygon is in the boundary of the MultiPolygon. Shapefile polygons are constructed from one or more closed rings.
