I did something similar. Wanted a Pixel with Graphene OS but the screen hurt my eyes. Went with a Motorola with an IPS screen. Uninstalled or disabled all the crap. Never logged into Google. Went with Obtanium and F-Droid for most software. Aurora for a couple of apps that were only on the Play Store. Used NetGuard with a whitelist to lock it all down.
After all that was done, the phone felt like mine in a way that my iPhone doesn't. Was a good feeling. With luck, the Motorola + Graphene partnership will produce phones with screens better than the Pixel and I can keep doing this.
