A What topics in Quantum Gravity don't require QFT or string theory?

Full quantization of gravity is a big issue, but that's not what I'm asking here.
I'm asking about quantum effects that involve any form of gravitation (Newtonian or GR) but that don't require a full quantization of GR or anything like that. Things like gravitational neutron interference or the Einsten Box thought experiment.

Newtonian gravity and GR are classical theories; by definition they ignore any quantum effects.

You seem to be asking for quantum effects that don't require a quantum treatment. That makes no sense.

Things like gravitational neutron interference or the Einsten Box thought experiment.
If you can find specific references about these things, you can start a new thread asking about those references. This thread is closed.
