As opposed to some photographers, I don't normally shoot with a specific monochrome aim. Rather, I will sometimes decide that a color image might do well in B&W or some type of monochrome that includes toning and, will then post process that image in monochrome.
However, in my film days., I was quite into monochrome (I had B&W processing and printing set up in my personal darkroom) and I had a variety of contrast and correction filters that I would frequently use. I loved the red filter for B&W landscapes. The limitation with that technique is that once an image was shot using a filter, it could not be reverted. We in the digital age, have the freedom do do just about anything we want with an image.
About the closest thing to shooting with the limitations of film is when I use my old Canon 60D (note: not the recent 60D) which I had converted to full-time infrared. However, this means that I need to carry an extra full size DSLR on my photo jaunts if I want to capture both "normal" and IR imagery. I really wish that I had a smaller camera modified to full time IR. It would be easy to slip into the pocket of my photo vest to shoot IR when I desired...
I can do a pseudo infrared processing on my color shots but, they don't come across as vibrant as a true infrared image that has been converted to B&W; such as this one...
