I keep seeing apps like these, and what they almost never have is sharing notes between multiple people.

I use Apple Notes, and I constantly share notes with my wife — and entire folder structures, too. We use it for grocery lists, dinner planning, travel planning, and many other things. It's not quite as elegantly real-time as Google Docs, but we don't need that as much, since we tend to edit at different times.

I also like that Notes is rich text all the way. My heart sinks when a new note-taking app boasts of Markdown support, as if that's a good thing. I think Markdown is fine for technical docs, where no good standard for rich text editing exists. But Markdown is a compromise — things like asterisks and underlines are less legible than the bold and italics they represent (especially across more than one word), and links become nigh unreadable, not to mention things like inline images and tables.

I previously used Evernote, and I've tried Notion (slow, awful for organizing, "block model" gets in the way of writing). I've yet to find anything that matches Apple Notes.
