There is no magic bullet. There is no one connection that can say, “Yes! We are destined for each other: YOU ARE THE ONE.”
Aspects between charts, and in composite, tell what type of energy is present in the relationship- but not whether that energy is right for you. Rather than searching for “good” connections, look for the connections that give you what you want.
What you want in a relationship, what will make you happy, isn’t necessarily “Their node on my Venus.” Relationships don’t need to be full of karmic ties and baggage to be right for you. Starting fresh- with someone you’ve never met before, someone with few, if any, nodal connections- might be just the thing.
