> What about when my notifications are showing up on my MacBook next to the phone via mirroring?
replySee perhaps §iMessage and §Continuity in Apple Platform Security:

Those notifications are transfered peer to peer (from your Phone to your computer) using Apple Wireless Direct Link. The contents are encrypted using AES-GCM.
replytalking totally out of my ass, but apple seems to have robust infrastructure for e2ee communication between your devices, for example it is known that location information in find my is not visible to apple. I’d be surprised if the channel to send iphone notifications to your mac wasn’t also e2ee
replyUnless something has changed since I last did this, the app's server initiating the apns doesn't encrypt using some public key for the destination. So no e2ee at that layer. But you could encrypt the payload and have the app decrypt it if you're managing the keys yourself.
