I use SSHFS every time I log into any of my computers.
Any file of any importance is on my RPi 4 headless server. I have a script that mounts the RPi server to a mount point (enosServer) in the home directory. This script is in auto-start. Every time I log in, Boom there is all my data in a local directory.
The RPi 4 server also has minidlna and acts as a media streamer for audio and video.
I also have a directory on the Server named “relay” that I use to transfer files to and from any computer in the house.
