stdin is usually closed, but can be connected to a TTY, socket or file: https://www.freedesktop.org/software/systemd/man/systemd.exec.html#StandardInput= stdout (right below stdin in the docs) goes to the journal by default and I would not touch it (because you need to log with the journal API instead of stdout then).
