I had considered this. Maybe a steel box frame inside for support.

Thankfully I'll have a brother-in-law and nephew nearby who are both pretty knowledgeable.

Sounds like solid advice. Thanks! One downside of the old home place is tight clay soil with a high shrink–swell capacity. Over time it can beat up underground structures pretty viscously. This is probably a 1940s era structure. There are also two remaining underground cisterns that I need to check to see if they will hold water.
Where i to fix it i'd seal the cracks with a cement/sand mix, first from the inside, so make it thick and sticky. Wait for it to harden and fill it from above with a sloppy mix. Push it in with a small stick.Fill it completely. Wait a day for it to harden. That will keep the water from coming in and worsening the problem. Then phase 2 bang the loose render of the wall with a hammer and render the walls. Phase 3 lock on the door so kids can't come in. Phase 4 keep a close eye on the repaired bits, if cracks don't open i wouldn't worry too much about it being unstable.
If you're unfamiliar with what i'm saying call in a expert to do the job.
I believe it's concrete over brick around the sides. I don't see any evidence of rebar or wire in the curved top.

I'd put this as phase 1. It sort of goes with the First Aid mentality of ensuring no further hazards or danger before starting.
Phase 3 lock on the door so kids can't come in.
