I am French, and honestly I can't remember a time when the knowledge of Latin helped me with something, and my undergraduate degree had a small component of literature (like two hours a week) so I had to study a bunch of classical French texts.

I think Latin might be interesting for someone who likes to study languages for the sake of learning them, or maybe for someone who is really into the Bible or the Roman history, but I can't think of much use of it. (You might be able to learn Spanish if you have studied Latin beforehand, but that time would have then better spent on learning Spanish).
