Picard, and to a lesser extent, Sisko got great development. They tried with Janeway.
I think he changes gradually, e.g. he recognizes T'Pol skills at the end of the pilot or learns the equivalent of the Prime Directive from Phlox in the first season.
But the experiences with the Xindi have most likely had the profoundest impact upon him as he learns to take enemies seriously and forge alliances whenever possible. One could claim that the Xindi crisis is a precursor of the Romulan War in terms of these two elements, fight for your survival together with those who are also (perhaps more mildly) threatened.
