When you go above 450V electrolytics they get pretty expensive. As a rule I always keep a few 600V 10mFd and 20 mFd caps on hand, but most of my electrolytic stock is 450V. I do keep a small number of 16V, 50V, and 160V electrolytics for the occasional (ick) AC/DC set I work on.
630V poly caps are what I (mostly) use for all cap values below 1mFd. The poly caps are physically too big when they exceed 1mFd. I do keep a small number of .0033mFd, .033mFd, and 0.1mFd that are rated over 1000V for some applications.
Oh yes, I also use ceramic caps for values from 10pF to 4700pF. (Yes, I overlap the poly .001, .0022, and .0047 caps.)
