Brothers engagement food

Dureen • Here to track my periods and save my good underwear.
For my brothers engagement ive been put in charge of desserts.  Ive been asked to make 3 different types of slices but im not sure what too make.  There will be people their from about 6 - 80.   What do you recommend??  
​Im an experienced cook and i can make "hard to make slices" as well as easier ones.  What ones should i make? Would live to hear what you think! :)
