I love docspell.

Try out sharry. Sharry is a self-hosted file sharing web application.

It works pretty well for my use cases. I also like the alias feature, what is pretty much what you are searching for. The only thing I miss, is the possibility to download a share as a zip folder. But there is an open issue for it, so maybe it will be added in future (again).

Bitwarden has a cli tool which I find pretty useful. Together with jq you can even pipe the password or store it to a variable.
