I'd just use the system mode. There's not much of a difference between
a system daemon and a daemon that isn't technically running in the
system mode but accepts connections from multiple users.

If you really want to avoid the system mode, you need to make sure
module-native-protocol-unix creates the socket in a place where other
users can access it (/var/run/user/1000/pulse/ is not accessible by
other users by default), configure the authentication so that other
users can get in and configure the environment of the other users so
that they know where the socket is (by default XGD_RUNTIME_DIR is used
to find /var/run/user/<uid/, but you can also configure "default-
server" in client.conf or set the PULSE_SERVER environment variable to
point to an arbitrary socket location).
