Is there a VSCode extension that implements Notion-like features?

Context: In an effort to be more organized (and out of sheer necessity to deliver md documents), I've been forcing myself to use Notion for the last couple of months. After moving one huge Markdown file from Notion to vscode to edit and format it there, I noticed just how much easier and more productive it was to not have to deal with Notion's plethora of subpar editing quirks. [Also, its startup time is absolutely ridiculous, and it doesn't even hide the window on Cmd-W but destroys it instead, leading to another "startup".]

Question: Is there a vscode extension that carries over some of the strong points of Notion-like tools (edit: or anything similar aimed at technical writing)? e.g. a hierarchy of pages, links to pages, inserting using / (forward slash), easy previews, maybe even simple page publishing+sharing?

Caveat: I know about org-mode and I used to be an emacs fiend, but I abandoned that world several years ago and I don't plan to come back.

Edit: I'm 90% sure HN changed "vscode" to "VSCode" in the title -- that's pretty neat.
