file manager options for user home directory

Looking for some expert advice. I need to provide an upload and file browse capability for a user's home directory. It doesn't have to be a full blown file explorer necessarily, just a basic upload, download, rename, delete. What's the best way to deal with the userid issues on Linux? The files live in a user's home directory, so the files are owned by the user, not www-data, and it's probably not an option to set the default group to www-data. Users can remote desktop and/or ssh to their account, so no predicting what user/group creation will happen behind the scenes.

I've thought about different options, but they all have tradeoffs:
1. dav enabled nginx process for each user with a javascript dav file explorer?
2. django-storages with sftp?
3. something else?
