I would like to find some way to improve their reliability - maybe with another app?

Push notifications are more reliable. You can check for changes from a server or a PC and send push notifications when needed.

Check the energy savings on newer Android versions. Non system apps (like yours) are not allowed to run in the background by default.

Even better

Not sure I exactly understand what a "system app" is - one of my apps runs as the default messaging app (i.e. replaces the normal SMS app) on a dedicated Android device - is this a "system app".

A system app are the apps built-into the phone when you buy it (not counting the built-in bloatware apps)

I used a lot of the guts of this as the basis for the apps I wrote.

I looked at this mechanism before I wrote these apps but came to the conclusion that the extra complexity of additional accounts and 3rd party servers - which need to be maintained, documented and explained to users - was too much.

I was looking for the simplest possible solution within the "AWS bubble" I have to work in - and came up with simple periodic polling - not as elegant probably but way simpler.

The only real issue is the annoyance of the odd failure of the StartServiceAt mechanism - which the SMS alert mechanism provides a workaround for - and which I was hoping to improve by raising the question in post #1.
