Shades of meaning
Fernald has no entry of its own for good-natured; he lists it under amiable, pleasant.
Where he writes about it:
Amiable combines the senses of lovable or lovely and loving; the amiable character has ready affection and kindliness for others, with the qualities that are adapted to win their love; amiable is a higher and stronger word than good-natured or agreeable. — from amiable
Kind, good-natured people may be coarse and rude, and so fail to be agreeable or pleasing; the really amiable are likely to avoid such faults by their earnest desire to please. — from amiable
The good-natured have an easy disposition to get along comfortably with every one in all circumstances. — from amiable
Pleasant keeps always something of the sense of actually giving pleasure, and thus surpasses the meaning of good-natured; there are good-natured people who by reason of rudeness and ill-breeding are not pleasant companions. — from pleasant
A pleasing face has good features, complexion, expression, etc.; a pleasant face indicates a kind heart and an obliging disposition, as well as kindly feelings in actual exercise; we can say of one usually good-natured, "on that occasion he did not meet me with a pleasant face." Pleasant, in the sense of gay, merry, jocose (the sense still retained in pleasantry), is now rare, and would not be understood outside of literary circles. — from pleasant
