I know this isn't exactly the answer to your question, but it's sorta adjacent and might be useful.
Pixel devices can run a number of Roms that go much longer than Google's support period (DivestOS, PostMarketOS, Lineage, etc). Older models can probably be found on sale from Google for ~$200 occasionally or even cheaper used, and with Lineage offer a really long support period on an OS that resembles AOSP with or without G Services.
