The logical place for per-user stuff would be /run/user/«userid», as per
systemd conventions.

On our companies user-access shell server, each user has their own /tmp
in their own chroot.

I once had to set up a file-access server for a client that had to support
both old-style insecure FTP and also SFTP (with the ultimate aim, of
course, of transitioning all their customers from the former to the
latter). Setting up a per-user chroot that would work with both was ...
quite a challenge ...
