Not sure how you all feel about .pdf’s, but since the majority of the content I consume is from the web, I’ve started saving web pages to Zotero, along with a .pdf generated using this clipper for Chrome.
I can then annotate/highlight the document and export all the content to Obsidian using Zotfile/MDNotes. There’s a bit of a learning curve with those two, but it’s been well worth it in my opinion. I prefer the much lighter .pdf to the output from MarkDownload, although I do use that on occasion as well (mostly for small extractions, like @N1755L mentioned above).
The advantage with Zotero is that in addition to the .pdf, you can also save an .htm snapshot of the page for later review if needed. I’m much more confident that I captured everything from the page, and didn’t miss anything in a conversion.
I haven’t tried this, but since I export the annotations and notes into Obsidian, I haven’t had the need to.
