Examples that come to mind:

• saying your favorite video game is Disco Elysium
• saying your favorite TV show is Star Trek DS9

The two rules are that:

1. It has to be to do with a category that is socially acceptable to talk about with most people in a casual setting. So no politics or philosophy.
2. Nothing too on the nose, ex, no "I love the music of the Red Army Choir" or something.
