I’m not interested in news but I love reading blog posts, newsletters and interesting technical discussions on HN or reddit.
So I built KTool as a “read it later on Kindle” solution. It supports web links, newsletters (via email forwarding) and RSS. I also added the ability to compile multiple articles into one magazine/ebook and deliver them at a specific time.
Give it a try if you’re a Kindle owner.

It could even be paired with an AI summary service that could summarize Reddit/HN activity, like Huxe does in it's generated podcasts.
This gives you full access to upload whatever ebook you want (SSH, WebDav, Syncthing, ...) and it can fetch RSS feeds (i use it with FreshRSS.)
PS. The (very old) Kindle Oasis is still the best device there is to read on in my opion. Which is crazy, since it was released from 2016-2019...
It has 2 phyisical buttons to turn the page, and an ambient light sensor to auto adjust the brightness, and a 300 PPI display.
I'm still "waiting" for a better / equal device to be released.
Koreader is well supported and has all the features you mention.
