The pixel phones (and the nexus phones before them) tend to be a little easier on those who unlock bootloaders and load custom ROMs. I use LineageOS on my Pixel, with OsmAnd maps and no Google services. https://lineage.microg.org/

It works quite well! Having not used 'normal' Android (anything that's not Lineage/Cyanogen) for years, I attempted to start out using this phone with the stock Google Android build. I disabled all the bundled crapware (Play Music, Play Movies, Play Games, YouTube) and they all kept re-enabling themselves. If you're looking for a device that will help you avoid Google at least a little bit, look at this page first. https://wiki.lineageos.org/devices/
