CAP_KILL seems a bit too much privileges for the sole purpose of being able to make ExecReload= work. Use the + prefix on ExecReload= instead to run "/bin/kill -HUP $MAINPID" with full privileges, ignoring the restrictions from CapabilityBoundingSet=. See https://www.freedesktop.org/software/systemd/man/systemd.service.html#ExecStart= for further details about the + prefix in ExecReload=.
