Pixel and GOS , very easy to install. Warranty blaha. Oneplus usually have a lot of lineage support. Spend and afternoon on YouTube , XDA forum and learn.
All of your brand's listed are bloated. Samsung is really bad though.
Sony phones come with stock android. Former Pixel user; been very happy with the Xperia 1 IV.
You have three options:-
Use a tool like Universal Android Debloater to disable (but not completely remove) them.
See if you can get Nokia or Motorola phones. These have mostly vanilla Android.
Get a Xiaomi or OnePlus phone with a custom ROM pre-installed.
I'm going against every one of your requirements by suggesting a pixel 6 or onwards used on eBay and install graphene os, it has the least amount of bullshit and is stupidly easy to install even for someone who's never heard of a custom ROM
