I didn't have any experience with kids before I started teaching 4th/5th grade. I was a philosophy major. My wife teaches High School English, and was an English major. She loves teaching AP classes, and has looked into starting to teach at the community college level as a potential fun thing after FIRE.
You might enjoy it more than you'd think (and if not, no harm changing). Teaching English language (to someone who speaks a different language) is vastly different than teaching English content, however (I.e. her class read Great Gatsby this year, and now are going to see the movie, not likely you'll do stuff like that, the high level analysis stuff she enjoys, while teaching English language, rather than English literature). But she's also potentially looking at teaching English in another country as well, so explore and be open to things.
And she also does an editing side-gig and wants to maybe get more into that after FIRE. Being able to write is an asset in general.
