What's your budget?
TBH, any modern-ish ereader with WIFI and a frontlight will meet your needs. If you have a home WIFI connection, or can use your phone as a hotspot, you can email ebooks to your ereader.
The
Kindle (2022, 11th gen) is 120 bucks on Amazon. Likely the cheapest brand-new option.
You should be able to find a second-hand
Nook Glowlight (v3 or V4) or a
Kindle Voyage/Paperwhite for around 60 bucks on ebay.
