I’ve also had issues with this. I have my own theories as to what might cause it in addition to yours. One is if a calendar reminder notification comes up at the same time as your alarm starts it will stop the alarm from making noise. Another is that I use a wireless charger that has my phone sit vertically and if I have it face at me my phone thinks I’m looking at it when I’m sleeping and will stop the alarm noise. Turning my phone away from me when I sleep seems to have helped. Another fix I found is to make sure that your alarm includes vibration, that way if the audio of the alarm doesn’t get you in time the vibration of the phone might.
