Boox Go 7 (B&W version) or Boox Page (discontinued) if you're willing to go Android. Both have the Oasis form factor with two physical buttons. Battery life is more like 1.5 weeks but hasn't been an issue for me at all. For me, I wanted Android after my Kindle to use the same apps I use to read books (or saved articles via self hosted Karakeep) on all my other devices.
