I've heard and seen both techniques too. My thoughts on that are to consider that the grain filler is always going to be very soft in comparison to the wood. You can let a small bit of grain filler dry for a week, and it will easily crumble between your fingers. So think about whats going to happen if you sand or steel wool after the filler dries. I just buff it very firmly with the burlap cloth, until the cabinet is almost shiny, then spray toner. But that is my technique, you gotta decide what you want to do.
