User=nobody will cause the unit to fail to start on systems where that account/group is absent, and it also uses a widely shared identity (less isolation between services). Consider switching to DynamicUser=yes (preferred for sandboxed services) or documenting/creating a dedicated iperf3 system user (and optionally set Group= explicitly).
