In the first case labeling a practice "best" may prevent learning or change for the better.
For the second case, if there are trade-offs that depend on context, then you pick a practice that fits them to the best of your ability, and I see little value in labeling it "best".
You may have practices to follow as a requirement - say, for space hardware. One could call this a best practice.
