What’s a good first drink for a fresh 21 year old?

My 21st birthday was last week and I’ve been wondering what a good first drink to get is. I’ve looked at the alcohol aisle in my local store and I am stricken with decision paralysis. There’s a lot of choices and I am very unsure of what’s good or what isn’t. I know “good” is subjective but I wanna hear opinions and differences.

What would you recommend for a first drink?
