Turning 21 tomorrow, what’s a good first drink?

For reference, from the sips I’ve had, I enjoy the taste of wine and ciders. I’m not a big fan of beer, whiskey, or champagne. I’ve tried vodka and tequila cocktails before – they were fine. I’ve never had a full drink before, so I’m not sure if that would change the experience.

Also, I don’t know if this sounds stupid, but while I’m excited to try a full drink, I have a personal policy to avoid getting drunk, so I’m worried that one drink will get me to the point. So, I’d like to try something lighter?
