Hello Rod,
It would be interesting to see both the systemd unit and the complete AVC message. You can retrieve the latter using:
# ausearch -m avc -ts recent
just after triggering the error.
Another thought: since you are using a script in a specific user's private bin path, it might be better to use a user specific systemd unit as well.
Otherwise, use a system-wide path for the executable (I'd suggest /usr/local/bin), and a system-wide unit (as you already do).
