I've tried a few apps on your list. Agree that Zim lacks polish, and that the Windows version is a few versions behind the Linux version. However it's really easy to import a bunch of plain text or markdown files (with .txt extension...just dump it in the data folder and restart) Standard Notes puts a lot of emphasis on security but doesn't yet have native support for inline images. Tagspaces seemed more like a file organizer that had word processing features tacked on. OneNote...I wish they'd restore the ability to use notebooks locally, the newer version wants everything on OneDrive.
