At least on Android, you can make TTS go through your alarm channel on your phone at max volume, to really make sure you don't miss it. I do this for my alarm and doorbell (only when I'm at home).

I have done this for my leak detectors.
Almost everything else obeys DND, but water? That's gonna wake me up.
I do the same (except on Android instead of iOS) and it works great. I have the alerts go to all our TVs (via our Nvidia Shield boxes and https://www.home-assistant.io/integrations/nfandroidtv/) and Google speakers too.
Recently had one of the leak detectors detect a leak and the alerting worked great. Turns out the leak was a bottle of distilled water dripping out the back of the bottle.
I've struggled with getting my TV notifications to show an image because I can't seem to get the URLs right. Is that an issue you've had? Any ideas on a solution?
Put the image in the media directory in your Home Assistant config directory then use /media/.... as the URL. This works for me.
For my security cameras, I have a Node-RED flow:
It:
- Listens for MQTT events from Blue Iris
- Builds a message based on the AI detection result and camera name (e.g. "Person detected at Front")
- Write image file from MQTT event to
media/alerts/directory - Send notification to phones and TV (currently just goes to one Shield - I need to set up the second one eventually)
- If a person is detected, send notification to Google speakers
Here's the JSON for the flow:

I did not know that you could send notifications to an Nvidia Shield. I’ll have to look into that this evening. Thanks!
It works well, and the TV app is free: https://play.google.com/store/apps/details?id=de.cyberdream.androidtv.notifications.google&hl=en_US&gl=US, you just need to download it from the Play Store on the Shield. There's a companion app for phones that costs money, but you don't need that one - it's only for sending messages from your phone to the TV.
Set it up last night. Can confirm it was quick and easy. Thanks!
