Romanticism is an international artistic and philosophical movement that redefined the fundamental ways in which people thought about themselves and about their world, whereas neoclassicism draw inspiration from the "classical" art and culture of Greek and Rome. I would say that, out of your list, Romanticism is: enjoys the mysterious and strange, prefers untamed nature to rule conscious society, expresses a tone of melancholy because time does not permit full realization of ideals. I think the rest are neoclassicism.

Hope this helped!
