I honestly get where you’re coming from as I went through a similar process of hating Windows, trying to make Linux work for me and just ending up back on Windows. I finally settled on Nobara Linux, but in my personal opinion it might be worth looking into Linux Mint for you if you want a rock solid distro. I installed Mint for my girlfriend not too long ago and everything magically worked with Nvidia drivers, wallpapers, Discord screen sharing, etc. I was so impressed that I considered distro hopping one last time.
The Pixels get 3 years of major version upgrades and 5 years of security updates from Google. After that point if the battery is still working well enough for you, you could always try installing something like Graphene OS on it.
