Interesting topic: I am marketing a "500 years of the guitar" program to schools, and finding short, punchy pieces to play has been the goal. From the Renaissance, Greensleeves works well because it's a recognizable Christmas tune as well; Dowland's Mrs. Winter's Jump, and Dlugoraj Finale is a killer scale shred piece that takes a lot of chops but is really exciting. Baroque era gives us Sanz and Bach ( the famous Em Bouree is always good). Classical era gives us some tuneful and flashy stuff by Giuliani, Sor and Aguado, among others. After that we enter the romantic period, with lots of Spanish stuff available from Tarrega's works and transcriptions, along with flamenco pieces. A couple of Sevillanas or a solid Farruca is doable by classical players. Once you're into the late 20th century or early 21st, it's time to create of learn a couple of arrangements of pop tunes: Beatles, Santana, Bruno Mars, etc., for the school market anyway. It's really good to finish off with something the kids know, even singing something is a winner, especially if they can sing along, great way to close. For adult audiences, there's a wealth of contemporary music that's upbeat and fun, especially Latin American pieces.
