Gotify

You can self-host a notification service using https://gotify.net/ for example, but you may need to ask the user to disable battery usage restrictions if you don't want the OS to kill the background process.

Firebase Cloud Messaging

The reason so many people guide you to Firebase Cloud Messaging is because unlike other options, FCM is made by google, and utilizes Google Play Services, which is installed on most Android phones by default and has VERY high permissions. This means it can always receive and process calls from Cloud Messaging - https://firebase.google.com/docs/cloud-messaging/.
