I sincerely hope they go back to AAA CPU. The mid range chipset belong on the March releaser. We should get a refresh CPU at that in October. Like the OG Pixel had - not SD820, but 821!

Also, I hope Google won't take something bad like the bottom-firing speaker on Pixel 4 and make it even worse (to basically no speaker / mono-mode on Pixel 5).

Now, I know this isn't popular but I would like to see the return of radar or dot-projector. Not for the silly gestures, but for face unlock. Selfie camera backed face unlock is insecure and clumsy, but the way it was on Pixel 4 was certainly the way to go.

Rear-mounted sensor is handy only on the go if you're holding the phone with one hand. In pretty much every other situation (phone laying on a table, in a wireless charger etc.) under-the-display fingerprint reader makes makes more sense. Or my favorite, trying unlocking or logging in some app using your finger with reader at the back while your phone is attached in a car mount... Also, sonic > optical.
