I’ve enjoyed using the Simple Alarm Clock on F-droid, importantly for me, it requires you to hold down the shut off button for a couple seconds which helps prevent me from accidentally shutting off my alarm instead of snoozing it. Only downside for this app and possibly others is that they may not function if your device OS updates in the middle of the night.

I’ve decided due to running into issues as well, that my system being built on x11 for a few years means I probably wont switch to wayland until I do a fresh install to avoid any potential issues around old x11 packages i’m running
