I’ve used Pocket for a while, before giving up (poor search, cloud based). Their mobile apps are great though. For now, I have resorted to Joplin (a note taking app) and its web clipper. It ticks all your boxes, except maybe “independent of the browser” (the clipper is a browser plug-in). Joplin itself has tagging, and you can reference your web clips (which are just normal notes) in any way you want, for example summarising and collecting related notes in a dedicated extra note for that topic.
