Read-it later, RSS & newsletter App

I'm looking for solution for several problems... I was using Omnivore, which was almost perfect, but since that one doesn't work anymore... I'm looking for Android app: - save articles for later reading - send newsletter from e-mail, So I can read it later as well - highlighting (?!) - amazing would be rss for follow newspapers which I want to read (I'm really tired of checking what's new or pending on social media to let me know) - communication with obsidian (?!) - reasonable pricing

I know I'm probably looking for an unicorn, but maybe you know about something, have some good experiences? I was checking Feedly (closest to my wishes, but still not perfect, too much mess I'm not interested in, price quite high), Inoreader, Feed me, NewsBlur (setting up newspaper email doesn't work), Feeder... Nothing looks like IT.

Any tips?
