This is what I do as well. 3 alarms at 15 minute intervals reoccurring everyday I need to get up on time. With a shortcut tied to the action button to turn them all off if I get up before all 3 go off.
And an automation to turn them back on at night on the important days in case I forget to do it myself.
The wake up alarms are buggy garbage. I only use the ones in the clock app and just make them recurring every day. Those ones can be trusted.
