I was under the impression that the public ntfy.sh server uses FCM and does not require using the instant delivery method.
Was I wrong?

I assume this is on Android?

I think if this was a widespread problem, we'd see more complains. It definitely doesn't take hours or even minutes for messages to be delivered. Usually just a second. If the phone is in deep sleep, it may take a minute or two, sometimes longer. But rarely.

It does depend heavily on your phone, and whether or not you have disabled battery optimizations. Also check out https://dontkillmyapp.com/ for phone-specific optimizations.

I'm using LineageOS 18.1 and have excluded the app from the battery optimization.
Also tried clearing the app's data and reinstalling several times.

If I remember correctly, it started after restoring the app using Titanium Backup, but now whatever I do I can't seem to fix it :(
