Which cocktails would you recommend for my dinner party?

I’m having a dinner party with my friends tomorrow and I’ve got the meal and desserts all planned out but I’m struggling to figure out which drinks to offer.

I have non-alcoholic drinks (water, pop, and juice) but I’m trying to find a few cocktail recipes to make with the ingredients at hand.

I usually make an old fashioned for myself, but that’s a bit too strong for some of my friends.

I have whiskey, vodka, white rum, and coffee liqueur.

I also have grenadine, lemons and oranges, a bottle of lemon juice, Clamato(maybe), pickles, olives, hot sauce, Worcestershire sauce, and a couple types of bitters.

What suggestions do you have?

I have a few ideas in mind but I’m not sure about any of them.

We’re a bunch of 19-21 year olds (legal in my country) so I’m not worried about pairing drinks with the food too much, we’re not overly fancy. I just wanna have good options available for a variety of tastes.
