Disabling Google Play Services and Google Play Store on a phone does create some problems as, for some years now, Google does send important security fixes to Android devices via Play Store.

On Pixels you can install GrapheneOS which has amazing security and privacy and doesnt have any Google services. If you need them you can install Play Services and Play Store on GrapheneOS. They run without the elevated privileges they have elsewhere. They are just like any other app. They cant read your phone number unless you grant them the Phone or SMS permissions.
