Today I answered this question:
After some back and forth with the asker in the comments, I thought it prudent to bring up the point that composition would be better than inheritance in his design.
I searched the main site looking for a good question on the topic of "composition over inheritance" but could not find a good one with lots of useful information, examples, etc. that demonstrate the strengths and weaknesses and makes a convincing argument in favor of composition. I ended up linking to a good enough question but was not satisfied with it.
Is there a question on the main site that would be a good candidate as the canonical "composition over inheritance" question that would be a good question to which to link when writing answers that advocate for composition instead of inheritance?
If not, I will consider writing up a self-answered CW Q/A.
