I've written a lot about this, and I got so annoyed with bookmarking and highlighting services getting it so frustratingly wrong[1] that I wrote my own solution from the ground up in 2020[2], and I have never looked back to browser bookmarks or services like Pinboard, Instapaper, Readwise etc. which are built around bookmarking metadata instead of content.
It's amazing once you get the mental model, and if you aren't interested in using a service you can easily build something that suits your own needs over a few weekends.
My favourite part of this mindset switch is that it makes bookmarking user generated content[3] both sane and easy, and automatically enriching those bookmarks with additional metadata a breeze.
