Basically anything tech-adjacent - product, "business analysts," management. Maybe something like tech writing but there are going to a lot of decent devs who make terrible tech writers so that's much more on an individual basis. And then there's the devs who still code but that's not their focus - SDET, devrel, that sort of thing.

Devrel would actually probably be the easiest thing to get into with a few years' foresight. Building a following on YouTube, Twitch, Twitter/X, etc. will make it infinitely easier to land that first devrel role.

You bringing up teaching is a good point - I'm not sure about where I currently live but where I used to live you could get a substitute teaching cert basically by just passing the background check and having a college degree. It was pretty easy to get an add-on certification as well to teach your subject or closely related ones. I can't say what it's like everywhere though, and to be honest most of the people I know who have teaching degrees have left or wished they could. But if you can get a job and can deal with the bullshit you're basically set from a put-food-on-the-table standpoint.
