I often import information from Google News into Joplin but unfortunately the way I do it is the way you suggest to Quick Share and then I select Joplin and what it does is Add a new note with the URL to the news article. It's efficient and simple but doesn't cover all of your bases.
On Android I found another workaround that is an extra step but it gets the job done for me and that is to share my news article to the Firefox web browser or just already be in the Firefox web browser for Android and in there I have installed the obsidian Web Clipper extension for Firefox and you can configure it to either paste the captured text and web page directly into obsidian which is what we don't want or in Firefox the obsidian Web Clipper can be configured to Simply copy everything to the clipboard and then you can go into Joplin and paste it wherever you want.
I'm interested in seeing into the development of a Joplin Web Clipper for Firefox that runs on Android. That's a missing component right now.
If Firefox on android had a Joplin Web Clipper both of our needs would be met. I think.
