Like Tim, I think the options available to you in Silver Efex Pro are only starting points. The really nice thing is that you can start with one of those points, or from a simple desaturation and work up whatever preferences you have for contrast, brightness, structure (grain), etc., and save those as your own preferred choice. In other words, with a good subject shot, you can create the same look you now get with film. It may take some time and tweaking and experimenting, but once you have what is essentially the same "chemistry" working, you should be able to apply however you wish to images.
There are going to be some differences in tonality, but that will be more controlled by what the digital camera is able to deliver. THAT part is both camera controlled and processor controlled. I found that I was getting way better conversions in some RAW converters like RAW Developer and even C1 than from ACR. Those become your starting points for further work with something like Silver Efex Pro, which requires you to work from a color image. I think the tonality control, in this case, comes from RAW conversion that preserves or delivers the most DR and stuff that your camera delivers to your files. Things may look a bit flat in color, at first, but those become very important for extracting the best B/W renderings, I find.
As far as I know, there is no magic bullet on the digital side to get things quite as easily as you may now get from some specific film choices, but I think if you take some time, experiment with things a bit on good RAW conversions, you should be able to get the look you want, and once you have that, it will be a lot easier going forward.
