If you need a phone that last long you should get a base varient of Samsung S23/S24 with 256GB storage. It checks most of your boxes but the main reason for suggesting Samsung is the repair parts availability after 5+ years also getting a repair outside warranty won’t cost you a fortune. Just debloat it and you are good to go until you hard reset.

Don’t do that, PC usb ports can break the charging port as the power output is unregulated better use some 5v1A rated charger

As far as I know Motorola and Pixel are the only OEMs with no ads or bloatware. For samsung you need to debloat and turn off notifications.

Their ads are mostly self promotion and bloatware apps. In my device I had to turn off notifications for most of the pre installed apps.
