Besides reception of the Eucharist and the readings. ?? I'm thinking ceremonial bits here, like asperges, incensation, Gospel procession, elevations, per ipsum, etc.
Mine is the EF's asperges ceremony, very impressive, and the Asperges Me and Vidi Aquam are magnificent chants.
I also love a well-done incensation of an altar with an absolutely ridiculously smoky thurible.
