The terms 'wainscot trim' and 'waincot molding' tend to be used interchangeably and they are more-or-less the same thing.
Technically speaking, wainscoting trims are not necessarily always decorative and can be used as a filler with the main purpose being functionality, whereas wainscoting moldings are a decorative trim that could enhance the look of architectural wall elements in a room, they can even be used with a wainscot trim.
