Personally I think focal length is not relevant here - in my opinion great images exhibit a combination of three key criteria.
Technical
Processing
Creative
Of the three above, the one most often overlooked is
Creative....
Specifically:
Impact
Emotion
Story
Pareidolia
Composition
Rule of Thirds
Subject Placement
Colour Palette
Technique
Research
Get most of those right and an image will likely score well in competitions, regardless of focal length.
