i draw like this

 public static VertexPositionColor[] triVertices = new VertexPositionColor[0];
//
 if ( triVertices.Length > 0)
                {
                    GraphicsDevice.DrawUserPrimitives(PrimitiveType.TriangleList, triVertices, 0, triVertices.Length / 3);
                }

Haven’t work much with 3D, but one way I’d do it (perhaps expensive) would be to place two instances of the same model one with solid and the other with wireframe. Most likely you’d get some Z fighting though.

You could use a 2 pass shader, the first renders with fill the second wireframe.

You may need to expand the scale on the second pass by a small amount to prevent Z fighting.
