The choice is based upon your purpose for performing the exercise. Choose a metal and a non-metal to prepare the compound.
The least ionic type of bond is a covalent bond.
The elements that generally form ionic bonds are the metals and nonmetals.
Metals.
Usually, a metal and non metal combine and form an ionic bond. There are exceptions though, such as ammonium nitrate.
Na and Cl, Mg and O
All of the metallic elements will form an ionic bond with fluorine.

metallic bond is present in KCL because all metal have metallic bond.
This is an ionic bond between metals and nonmetals.

All group 1 metals and group 2 elements excluding beryllium will form ionic compounds with nitrogen.
Covalent or molecular compounds form when elements share electrons in a covalent bond to create molecules.
An ionic bond is between a metal and a non-metal. Calcium is a metal and chlorine is a non-metal, so yes they form an ionic bond as CaCl2
