The first thing I would say is that I do not have a clear definition of Romantic in my head. Â I have heard at least 3 different definitions.
This said, in previous discussion with a friend of mine, who is a retired professor of Music at Cambridge University and specialist in Mozart, it is the general opinion that Mozart spans the division (in time and style) between the classical period and the romantic.  Thus his final 2 symphonies, and final few operas are ever more romantic, from Don Giovanni, through Cosi Fan Tutte, and culminating with Die Zauberflöte (Magic Flute).  (His penultimate opera La Clemenza di Tito being a harking back to the previous style).
Similarly, Beethoven’s first two symphonies are thought of as classical, and his 3rd, Eroica, his first romantic.
One of Mozart’s contemporaries whom I would put in the same category of spanning the styles, and more fits the “undiscovered” moniker, is Luigi Cherubini.  He is rarely performed now, but was a prolific composer of opera and Beethoven is reported to have called him the greatest operatic composer of his time.  His subject were a mix of the classical (Greek/ Roman) and revolutionary/ rescue stories.  Medea (Medee in the French version) is his most famous opera as it was sung by Maria Callas (though it is not a good recording), and Les deux journées. He also wrote one one the great requiems of history.
