Exposure to all areas of pulmonary and critical care from a clinical standpoint is important if you are still somewhat totipotent, which it seems that you are. Some of the bigger places mentioned above will definitely be able to do this for you.
As far as a clinical educator track is concerned - that means different things at different institutions. What do you mean by "clinical educator"? Does it include research? If so, how much?
If what you mean by that is to be a great bedside teacher who also takes part in quality improvement, curricula development, etc - then what you are really saying is that you want to be an academic clinician. The difficult part is trying to merge interests in medical education with research. The main reason why that is difficult is because it is pretty difficult (without a clear road in view) to obtain funding to pay for research that is centered on medical education. Often, you have to merge it with health services or something like that to take more of a policy angle - or seek money directly from the ABIM or intramurally. Harder to provide a clear framework for those sorts of things on an interview day. Much easier to provide a framework for successfully obtaining career development awards in epidemiology, bench work, or health policy. Feel free to PM me if you want more on that.
Best of luck.
