One of the coolest new projects in the Apple II space in recent years is the The SMB FST for GS/OS, which allows an Apple IIGS to access file servers using the SMB protocol if you have a network device. Since it's a file system, the Apple IIGS treats it more or less like any system drive. You can save documents to it on any application, and you can even run applications directly from it.
I did have to modify my Rocky Linux samba configuration file to get full compatibility with GS/OS resource fork system. These lines were added to the smb.conf file:
vfs objects = catia fruit streams_xattr
fruit:encoding = native
fruit:metadata = stream
fruit:resource = stream
ea support = yes
streams_xattr:prefix = user.
streams_xattr:store_stream_type = no
Now, I don't know if all these lines are necessary, but it's working so I didn't mess around with them more.
