Because of how I learned "serious" photography using film about 30 years ago, I never intentionally shoot thinking that I'll make the B&W/color decision later. It is always a deliberate process with the intended final product in mind.
Except for a couple of experiments and demonstrations, we never created monochrome prints from color negatives. There were a couple of reasons for this. The first was that color negatives, even when exposed and processed properly, did not have enough dynamic range to make prints with good impact. The second was that our process was set up around "variable contrast," or VC paper, which depended on the use of filters which ranged from pink or magenta to orange to control the contrast of the final image. As a result of this non-linear color response, tonal values and contrast would be uncontrollably altered in our finished prints if we used a color negative.
I believe that what makes a good black and white photograph is radically different from what makes a good color photograph somewhere around 98% of the time. Exposure visualization is completely different between the two media. I've found that it is very difficult to produce a great b&w print from an exposure that was set up and exposed for color. The converse is also true, at least for me. Because of that, I always try to work intentionally and use camera setup options to reinforce my intentions. (That does not mean that I've never desaturated a color image to produce a black and white one, but it's not my normal approach.)
Unfortunately, I also think that today's display media (video displays and most modern printers) are really not that well optimized for reproducing really good monochrome images, so unless one has visited a really good gallery or museum recently, most folks today have not seen an outstanding b&w image in recent memory. As a result, we really don't know what we are missing when we view most digitally produced monochrome prints. As good as they are, most of today's cameras and software really treat b&w as an afterthought. It's one area where digital photography still does not match silver based photography, especially at the highest levels.
You will note from my frequent and intentional use of personal pronouns in this post that it represents my own education, experience, and preferences. It is certainly true that others may believe differently or have a different experience base. That's fine too.

There is lots of good information in Mr. Page's post. I usually don't allude to my long film experience for nostalgic purposes, but there is lots of old theory that is very applicable and relevant to digital photography.
I too, prefer to shoot in MONOCHROMATIC mode when I know there is a requirement for black and white prints or digital output for the same reasons I preferred to use black and white film rather than shooting color negatives and making conversion after the fact. Variable contrast papers, obviously, could address contrasts, they would not deliver a PANCHROMATIC rendition of the actual scene or subject. PANALURE paper for Kodak and PANADEX (bot discontinued) materials from GAF would address panchromatic concerns but contrast control was difficult as well as handling of the materials, in near-total darkness, was also problematic. The issue with NOT using a Panchromatic paper is an improper tonal rendering of colors in the black and white grayscale. The orange MASK in color negative film is part of the problem. As an example, a portrait made on color negative film of a subject wit blue eyes could show up on ordinary paper was very light gray or almost white eyes- very unnatural. Many other colors could be misrepresented. I also find this an issue when making the conversion from color digital files but not to the same extreme, but it is there.
There is the color/contrast issue which is common to film and digital photography. A classic example MAY be a red apple photograph against a blue background can possible registered, in monochrome, as the same tone of gray, this causing blending and loss of visual contrast. The remedy of this kind of problem is filtration- a red filter would lighten the apple and darken the blue, a blue filter would light the background and darken the apple. This can also occur with many other colors. In order to detect and prevent these issues, you need to SEE the tonal relation while shooting.
Then there is a wide range of aesthetics and effects that filtration can address. In portraiture, a green filter will enhance skin tones (in monochrome) and provide a faux-orthochromatic (very dramatic) rendition for theatrical and character studies. It will dark skin and lighten foliage in outdoor portraits. A light orange filter will produce a porcelain-like skin tone without further post-processing. Yellow, Orange, and Red filters will darken blue skies and emphasize clouds. without the effects of polarization.
None of this is to say that some of these issues and effect can not be addressed or produced in post-processing but I prefer per-visualization whenever possible and it sure cuts down on post-processing time.
So...back in the film days, I always lied to "choose my weapons" in advanced of each assignment, especially in black and white requirements by picking out the best film and developer combination, filter when required, and of course, lighting elements. When black and white AND color was required on the same (film) job, I would oftentimes work with two cameras and if time permitted would even take different lighting approaches. Nowadays, it is easy enough to switch to monochrome when time permits.
