I'm in much the field as yours @QuimReaper and I agree that it is looking bleak in terms of academic employment, particularly if you aren't mobile. In terms of your personal set up, I can't help thinking you're actually quite lucky - as a single I always had to work, and moved several times to stay employed. And also looked at alternatives, as you are doing.
I managed to stay in my field, but I suspect I sacrificed relationships & the chance of a family to do so. In the year I graduated with my PhD, there were precisely 2 jobs in the entire country that I was qualified to apply for. I took one of them, taking a step downwards in status and moving several hundred miles ...
That was 30 years ago, so you know, I"m not sure things are particularly harder now (no post-docs in the humanities for a start). Just difficult in different ways.
You could go on to start developing British Academy & Leverhulme post-doc applications. Find a university near to where you live with a good research reputation in your field, and appropriate mentors. We've learnt from COVID that we don't need always to be in physical proximity - although sometimes is good.
Or start to think about what skills you have - not what you know, but what you can do. The daughter of a colleague of mine, with a very good humanities PhD from an excellent research university moved into a graduate training programme where her analytical skills were valued, as was her ability to analyse text and get to the nub of it - this was in financial management! So apparently miles away from her PhD topic, but her skills were valued.
Good luck!
