Admittedly, I've only done 3-4 rooms of moulding, but I just cut them a
little long and then trim until they fit.


That is definitely the preferred method. I try to do that one all the time.

But I have measured repeatedly, then cut the moulding too short. This is
followed by the obligatory profanity which is followed by a trip to the
store to buy more moulding.
