DisplayForm (or another function) is producing incorrect output in the
second case below. There should be no string delimiters shown.

By what reasoning? The input to DisplayForm is a set of boxes. The box
form of 5 is "5". Therefore, DisplayForm@"5" should show 5.

Note that if you try to test this with regular input and output, you
will probably be confounded by the "ShowStringCharacters"->False
option setting of the "Output" cell style.

CellPrint@ExpressionCell["5","Text"](*correct output*)
CellPrint@ExpressionCell[DisplayForm@"5","Text"](*incorrect output*)
CellPrint@ExpressionCell[DisplayForm@RowBox@List@"5","Text"](*correct output*)
"5"
"5"
5
