If you're interested in critical care/anesthesiology OHSU (Oregon Health & Science University) has one of (if not the ONLY) combined anesthesiology residency/critical care fellowship programs in the US. Definitely check it out if you're serious about critical care!
While that sounds appealing ... and I'm sure it's a fine program, I wouldn't put too much stock into it. Any good anes program will give you a robust critical care experience, and you can spend 6 months of your CA3 year in the unit if you wish. You'll then have the option of staying at your home program for fellowship or going to see/learn somewhere else.
As for paths to critical care and job options thereafter, I think anes is the best way.
Your options are
GS (5 yrs) + CCM (1 yr)
Anes (4 yrs) + CCM (1 yr)
IM (3 yrs) + Pulm/CCM (2-3 yrs)
Anes is the quickest. Along with surgery it also gives you essentially two entirely separate careers. Arguable, the anes OR skillset will be more useful in the unit than the GS or IM skillset as well.
Who staffs what ICU is highly variable by institution. My impression is that in most places, Anes CCM guys run units that have at least some surgical flavor to them - SICU, CTICU, Neuro ICU, etc. You're probably not well trained for academic MICU patients (HIV, oddball ID,etc.)
As for a community ICU - you can get a job anywhere doing anything coming out of Anes CCM.
