I’m currently using a Moto Edge 30 Ultra it’s basically completely AOSP Android the only stuff that’s pre-installed are the Moto Apps that are actually useful for the phone which also don’t have any ads and the phone has way better performance than all my stupid Samsung Exynos phones. So Motorola would be very good for what you’re looking for. If you don’t want to go with Motorola though I would recommend Sony or Fairphone.
