Nova messages is what I’m currently using the notifications are a bit weird but the app in of itself is great and polished and doesn’t seem that bad privacy wise it is as far as I’m concerned available on both Orion store and github Used to use quik SMS before it

Unfortunately Silence has been unmaintained for years now, so I wouldn’t recommend it.

qksms indeed

I’d say don’t bother and just go with https://www.f-droid.org/packages/com.simplemobiletools.smsmessenger/
