Ahhh, well you don't need SSH for that.
Of course you're right. And I should have focused on this earlier.
Because this is a system that I want to distribute publicly (it will require the user to drop a Windows 98 SE installation ISO on the application before it will run), I was looking for a solution that wouldn't require installing other software on the host. But again, you are absolutely right. I just installed a free FTP server on macOS, and was able to transfer files to and from macOS host and the Win98SE guest using the WinSCP client that I've installed on the Win98SE system. Presumably I can do something similar on Windows. This turns out to be very simple for an end-user to do.
EDIT: Yes, FileZilla Server worked perfectly for transferring files between Windows 11 and Win98.
When I go public with this system, I'll include the relevant instructions. Thank you again.
