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.
I ended up with a Motorola phone, too (albeit with an AMOLED screen so not the model you have). I got hooked on Motorola phones because of the "chop/chop" flashlight gesture. I don't think I can use a phone without that gesture ever again! >smile<
I'm hopeful, too, re: Motorola + Graphene. I wanted to use Graphene last fall wehn I got the new phone but I was committed to not giving Google any money.
This, but fortunately I don't find the Pixel screen offensive, and so I use Graphene on a Pixel.
