Non-Academia Classics PhD Opportunities?

Hello everyone, I am a current third year undergraduate in Classics. I absolutely adore the discipline and would love to pursue graduate school with the dream of being a professor. However, I have read countless upon countless horror stories and even speaking with my graduate studies advisor hasn't been too inspiring.

A part of me wants to do it anyways, but I also want to be logical in this decision. So, I am curious what people have done after grad school (Masters or PhD) outside of academia. I know teaching high school is the default answer, but I would like to hear about other opportunities and if you regret going to graduate school.

Any advice would be appreciated. Thank you.
