Honestly just install grapheneos on your Pixel, that is what I did and bought a Pixel for that reason alone. I use all Google play services and it works great, only payment with phone doesn't work.

Yes I agree: if you already have a Pixel, try GrapheneOS on it. Then if it can wait (Pixel 7 is still supported for a while, isn't it?), GrapheneOS may support a non-Google phone in 2026, so it may be worth waiting.
