Leave 'LogTarget=' to its default value (journal-or-kmsg).

Could you be more specific about which daemons are affected?

Many daemons that are started by systemd service run in foreground (don't ask
me about the logic behind this). This means that all output is sent to stdout,
not syslog. Journald collects this output and forwards it to syslog -- hence my
recommendation above.

For example, sshd(8) now runs with '-D'. Of course, some daemons might send
their messages syslog even if run in foreground, but not all.

A hard way to fix this is to modify service files for daemons you use to run in
background and set 'Type=forking'.

HTH,
