Help me build my bar at home

So far I purchased the following as a starter for my bar at home -

Smirnoff Vodka, Bacardi White Rum, Malibu Coconut Rum, I made a few batches of Vanilla Simple Syrup, Lemongrass Simple Syrup, i bought some Mango Purée, Pineapple Juice, Passionfruit Tea Puree, Lemon Juice, Lime Juice, Canned Peaches, Canned Lychees and Canned Pineapple, Coconut Cream

What else should I purchase that’s a must when building cocktails, something that i’ll most likely use often when experimenting on drinks.

I’m a fan of fruity cocktails, but am open to exploring other basic cocktails as well.

So far i haven’t really made anything yet since my tools are just about to arrive but would love to know if i’m missing any basic ingredient!
