SPSA should work way better in noisy environments.
Qiskit has It in the qiskit_algorithms package but the implementation is not straightforward due to the apparent impossibility to use a cost function containing not-to-optimize parameters.
PennyLane could have the solution but at this point I guess we should learn how to do QST in PennyLane first.
