I was not expecting v1.14 to degrade the vibrations, but I was expecting it to not increase them. As demonstrated in the comparison available at Same hardware, same MC parameters, but significantly different vibrations in hover - Where does this come from?, the vibrations are indeed different across PX4 firmware versions. I am still trying to understand what specific changes between v1.14 and earlier versions might explain the altered flight behavior, as adapting the notch filters did not solve the problem. The differences in vibration characteristics are even more pronounced when now comparing v1.14 with ArduPilot on the same hardware.
Here is the log file for the PX4 flight: https://logs.px4.io/plot_app?log=15bb12fb-5e52-4182-aed9-750d2fee19ef
