nanobind/pybind11 (co-)author here. The space of python bindings is extremely diverse and on the whole probably looks very different from your use case. nanobind/pybind11 target the 'really fancy' case you mention specifically for codebases that are "at home" in C++, but which want natural Pythonic bindings. There is near-zero overlap with Cython.
