So, once I saw the runway environment (and kept it in sight), I was ok to
descend a hundred feet, fly a couple more miles, fly the pattern, and
land,
right?


Right.



Or (if I had been in class G, below 700' agl) cancel IFR "real quick"?
Does
ATC have to hear me and respond, or is my call "into the blind"
sufficient?


If you have the runway in sight you don't need to cancel or request a
contact approach.
