How to share a folder in Linux? (mander.xyz)

I work on an HPC and often I have to share files with other users. The most approachable solution is to have an external cloud storage and recline back and forth. However there's some projects that are quite heavy (several TB) and that is unfeasible. We do not have a shared group. The following is the only solution I found which is not to just set al permissions to 777, and I still don't like it.

Create a directory and set ACL to give access to the selected users. This works fine if the users create new files in there, but it does not work if they copy from somewhere else as default umask is 022. Thus the only appropriate solution is to change default umask to 002, which however affects file creation system wide. The alternative is to change permissions every time you copy something, but you all know very well that is not going to happen.

Does it really have to be such a pain in the ass?

This is a good idea and something I may setup once we setup our own compute server. However at that point wouldn't a synced directory be a better fit for the purpose? Such as you define a directory on the external server to be used to share data and every user syncs it to their own share on the main server to get all the shared data through rsync or unison.

Just throwing it out there, I'm not sure if that fits your use case.
