Can anyone using GrapheneOS report if Firebase notifications come in consistently and reliably via sandboxed Play Services?

I'm in the market for a new phone, and I'm going to buy a Pixel 9a this week for GrapheneOS if I can reliably get notifications on it. (I already have an A05 for banking apps)

I'd be happy to check for you, but will need concrete steps. Signal working reliably is pretty much all I can confirm, since I don't use any others apps on that device that would give me notifications. Signal afaik uses this Google Cloud Messaging thing or whatever their TCP connection marketed as push service is called. Maybe that's now called Firebase?

But Signal can also fall back to websockets, which I use on my personal phone and that's working great without any battery loss so I don't know how to tell the difference

Yes, all notifications work fine with sandboxed Play Services installed. All my banking apps also work fine. I haven't really had any problems with app support or any other problems for the many years I've run GrapheneOS as my daily driver.
