If you are using s Mac you can just setup Apple Server and use it for a file server aka NAS.

Better to use iCloud as Optimized so it will be a remote file server that keeps local copies of only the files you are actively using. You have immediate access to the files you are working on, but still have the rest of your files stored in iCloud instead of locally. Apple is just making it so network speed doesn't effect the files you are actively working on. It may be a bit confusing because it really starts working when you run low on local disk space.
