I don't have good first hand experience, but i know the Awesome Selfhosted list has a plethora of them.
and copyparty is on there. it has everything they need.
That was the first place I looked.

it can do what you ask, except I am not sure for the last one
can’t see / download files already present in the shared folder
that seems a bit complicated. Unless the solution stores user permissions per file.
Not really. Nextcloud does this. They call it a "file drop".
Like you create a share link for a folder, and then specify that users of that link can't see any files, only upload.
Edit: looking at the docs this one seems quite good. Thanks!
AAAAH sorry I misunderstood your point before. I thought users should not see files prior to their joining of that folder, but see files that come in after their joining.
But you mean, users should only see files they upload, while an admin or so sees all files.
Correct.
Suppose you wanted students to upload assignments or something.
I'm gonna try out sftpgo when I have a minute. Docs say it does this.
I just tested it on my instance. You can create a public share by setting the mode to "Write", which is accessible without logging in as a user (but with optional password).
It works, but one does not see any files, not even the ones you uploaded yourself. So for example if you updated the file and need to re-upload it, there is no way for you to delete the previous one.
You can also create a shared "virtual folder" that is seen by multiple users, and then you have fine grained control on a user basis (Users > burgermenu > edit > ACLs > Per directory permissions) there you can mix and match from a list of ~15 permissions. To upload anything to that virtual folder, you'll have to properly log in as a user.
Hope either one of the ways works for you. Cheers
So for example if you updated the file and need to re-upload it, there is no way for you to delete the previous one.
if this is something you'd fancy then copyparty might be worth a look -- it lets uploaders undo their own uploads within a configurable timeframe, even in folders where they only have write-only access (the ability to upload files without seeing existing files).
disclaimer: I'm the author -- and also thrilled to see someone else suggesting it in the thread!
copyparty.
I've used Erugo a few times and been happy with it. Not sure if it does everything you need but worth checking out.
