Snap To Reference is indeed the solution.
Some of the vanilla cells are not based on the default grid origin (0, 0, 0).
For example, if you look at the X-coordinate of a vanilla reference, it might be 59.8596, which is obviously not a multiple of 2, so new pieces won't snap to it.
File > Preferences > Select Snap Reference > Select Reference in Render Window, then select any vanilla piece which is precisely aligned (such as a floor tile).
After that, all new pieces will snap to the vanilla grid.
Incidentally, does anyone know a way of forcing the vanilla pieces onto the default grid?

Turn local grid snap off, drag one piece until it snaps, then drag the other pieces to snap to that one.
