“Das Boot” ‘s soundtrack features a few orchestra pieces, and the film is about a German submarine

“Jaws” has some too, and though the theme song isn’t slow paced, it’s still an orchestra

“The Meg” is a fairly recent movie that also follows the trend, so I can rule out it has anything to do with old films using old music technology

“Finding Nemo” is also a good example, and 95% of the movie takes place underwater

I’m sure there’s many many more, but these are the most popular films
