Assuming the cables are reasonably made and well shielded, the differentiating factor between the cables is going to be the capacitance. The monoprice cables have a capacitance of 21 pF, while the bluejeans cables have a capacitance of 12.2 pF/ft. Both good, and reflect the price differential. Most high end cables would be worse than BlueJeans. Only a very small minority of high end/exotic cables would actually be able to beat the BlueJeans number. (Based on comparing products from Tara Labs product line up)
The big difference between RCA (unbalanced) and XLR (balanced) is that the balanced outputs of your preamp typically has twice the output voltage (typically 2V) as the unbalanced (typically 1V). This will give you some additional gain from the amplifier. However the input and output sensitivities of the receiver/preamp and the amplifier need to be well matched.
If the sensitivities are not matched you will end up with either hiss/noise floor issues (input voltage too high for the amp) or low SPL (not utilizing the amps watts because input is too low for the amp)
The upshot is, XLR cables might give an extremely tiny (audible?) improvement in interference, but can sometimes introduce a much larger problem of hiss/noise levels by raising the nominal output sensitivity of the preamp
