In practice, "well-intentioned" is most often used in constructions that acknowledge good motives while criticising outcomes: "well-intentioned but misguided," "well-intentioned but ultimately harmful." Having good intentions is the minimum expectation, not a sufficient defence. When someone says "the policy was well-intentioned," they are almost always about to explain why it failed or caused harm.
"Well-intentioned" is the standard, widely accepted compound. "Good-intentioned" is used but is less common and slightly informal. In formal writing, "well-intentioned" is preferred. Both mean roughly the same thing — having intentions that are morally positive — but "well-intentioned" has the richer critical usage, particularly in the "well-intentioned but..." construction.
A trick to remember it
well-intentioned = "having good intentions", from "intention" (the same word in "my intention was..."). The compound is completely literal.
