if we look at MTW Gravitation, on page 1054, they talk about experiments with elementary particles.
These experiments have nothing to do with light clocks, and do not involve the issues that your proposed thought experiments with light clocks are raising.

there is certainly an experimental basis on which I can assume time dilation in a curved spacetime
Only if you understand that a fundamental part of that experimental basis involves
how to compare the rates of different clocks that follow different paths through spacetime. There are only two invariant ways to do that:
The first way requires that the clocks are like the twins in the twin paradox: they start out together, separate for a while, and then come back together again so their elapsed times while they were separated can be compared.
The second way allows the clocks to be spatially separated, but requires that they are at rest relative to each other, as determined by the round-trip travel time of light signals between them, as measured by each clock, being unchanging. Then you can compare how much time elapses on each clock during one round-trip light travel time, and compare their rates that way.
So far, you have not specified a way of comparing different clocks in your proposed scenarios that meets either of the above requirements. Until you do, the questions you are asking are not answerable.

you can imagine me making two clocks right, same height, and I throw one into a black hole and one stops ticking
No, it won't.
