Yes you can achieve this with Pocket or Wallabag, a FOSS alternative.

Wallabag also have an automatic tag feature that can add tag based on the URL, so it would be possible to make different reading lists as you suggested: https://doc.wallabag.org/en/user/configuration/tagging_rules.html

I use an old standalone alarm clock, that I put on the other side of the room. So I have to get up to turn it off.

Which type of content are you after? I have a page where I curate nice pics on the fediverse. There is some nature photography, but not only: https://kevinronceray.com/notes/pixelfav

I am also on Pixelfed: https://pix.diaspodon.fr/@kevinronceray

You can find the link to join the TestFlight beta on their website: https://pixelfed.org/mobile-apps

I don’t know the current number of spots available for new testers but they post on their mastodon account when they add more.
