…coeefients and all two-qubit interactions i.e. XX, YY, ZZ between any qubit pair

I don't think you need to calculate the coefficients between all pairs of qubits, since not all qubits are coupled together, and qubits that are not directly coupled will have very small coupling values (as you can see in your example notebook as well). You can keep this method that you already have, just because ZZ between non-neighbor qubits may not be very small, but XX and YY will definitely be very small. However, please add the requested functionality below as well:

Modify the methods that I already have (full SW and PWSW) to include ability to calculate XX and YY couplings as an option. You'd essentially add an option to my previous methods, for example XX_YY=True, so that when this option is true in those methods they calculate XX and YY as well, and when it is false they don't do that (they just do what I initially had). Of course all these terms will only be calculated for qubits that are neighbor and coupled via a coupler element (not next-nearest neighbors).
