I don't know a ton about stadiums but I'll share my opinion and a few things. Progressive Field (formerly Jacobs Field) home of the Cleveland Indians has a home plate that faces pretty much directly north. As it was said most home plates face NE, thankfully the designers were smart enough to realize that the view of the downtown skyline would be best with home plate facing north. It is a great view of the skyline and a great park to see a game at.
As for AAA fields Franklin Covey Field, home of the Salt Lake Bee's of the Pacific Coast league, (Angels affiliate) has been rated as the best view in baseball. It faces SE and has a amazing view of the Wasatch Mtns over the outfield wall. It was also the first AAA stadium to be designed as a double deck stadium.
