I highly recommend Tchaikovsky's Nutcracker. Great music. There are also some dancers on stage, which some people may enjoy, and if you don't, you can always close your eyes. Go do it in person, not via video: the experience of the music shaking you is different than even good speakers. And the moment when the fog from the stage envelops the first dozen rows of the audience is magical.
If you are in Silicon Valley, there are two professional stagings this afternoon in San Jose: At the California Theater (with the professional symphony, but a smaller and less experienced ballet, much reduced orchestra), and at the Center for Performing Arts (with a semi-pro orchestra, including me, but the full set of instruments and a bigger and better ballet company). Both at 2pm. If you are further north, the San Francisco Opera one is fabulous, but also a longer drive, and a bit more expensive (that was a euphemism ... parking in SF alone is probably more than the whole show ticket in SJ).
