Friendship - Don't think so. Naruto basically forced his friendship upon Sasuke, completely ignoring his wishes (even though they weren't quite positive).

Acceptance - Kind of. Something like "born into hard circumstances, but still get respected at the end".

Hard work - Definitely no. Everyone who achieved his dreams in the series did so without hard work. Everyone important is a prodigy, a genius or simply born as the son of the Fourth Hokage, the incarnation of Ashura and the Jinchuriki of the second strongest entity in the universe.

Personally, I believe that the strongest theme was "Never go back on your words". Or at least that's what I liked the most, from all the possible themes.
