I think that's true about Bach's instrumental music, but his big sacred works like his Passions and the Mass in B minor are as "romantic" as the Baroque period gets. Like OP, I think of these works as basically the pinnacle of human artistic achievement. They somehow have all the nuance and complexity you're referring to -- while also telling a deeply emotional story, and just being heart-wrenchingly beautiful even if you don't know the story.
