Note: If the machine is dual-homed with multiple connections then you need
to use policy routing to have traffic routed correctly to the correct
connection. This is not a Squid issue but a generic networking question.
The problem is that normal routing assumes there is a single path which
should be used for all packets to a given destination and does not care
what source address is used. For this you need to use the ip command to
set up your routing policy.

If you only have a single connection but want to use different IP
addresses on the same connection then no policy routing is needed.

As you say the best method to select which of your links or IP addresses
are used by Squid is to tell Squid to use a specific address. Other
approaches only makes things more messy.
