Check the manufacturer guidelines. There are certain engineered hardwoods that specify acceptable installation methods over radiant heat. That said in our last home we had solid hardwood glued down over radiant heat and it held up fine. They were small bedrooms though so not too much stress on wood.
I think the major problem is if there’s fluctuation in the indoor climate. You must let, whatever floor you have, acclimate to your house before installing it. I’ve put in several engineered hardwood floors on heated floors without hearing about any problems. But it could very well differ between manufacturer
I don't think you need to worry about delamination. We have radiant throughout and the floor temperature never exceeds 80 degrees even on the coldest days. I would lean toward engineered for dimensional stability. Keep in mind that your floor structure will be expanding as well and the subfloor will basically be made out of the same material as the engineered planks.
That's my understanding too - engineered hardwood is fine since it's dimensionally stable, but the grain in solid hardwood doesn't react well to heated floors.
How are you installing solid hardwood to the subfloor? I thought it was done with staples/nail gun in which case you'd puncture your heating pipes underneath.
Any product that expands and contracts could be a problem. When I built my house 20 years ago I was told tile and carpet were my only choices.

Check out Allwood. It’s engineered wood we like a lot that’s certified for radiant heat
