I really don't want to be that guy, but isn't SSHFS (FUSE) actually a terrible option when compared to an actual file-system? MacOS isn't really missing out on much there.
The most painful part of MacOS (which makes it downright unbearable for me) is that system configuration files are XML. It's an absolute nightmare.
SSHFS uses SFTP which is built into SSH, so no server to install. Its not as fast as NFS, but requires no setup. For something small like a home lab, that is a big advantage.
For some (most?) of us, we don't have ssh access open to the world, so everything is over a VPN. So I can just use NFS over WireGuard which afaik is fairly secure, if you trust your endpoints, and works great over the Internet.
SSHFS is very mature. I use it for administering several home servers.
It works so well that they added a mode where some users can have SFTP only access (without SSH shell) so you can set up shared directories. It was easier to set up (for me) than CIFS or NFS.
