It can be either, depending on the reaction. Sodium chloride is a product of the reaction of sodium hydroxide and hydrochloric acid. Sodium chloride is a reactant in the ion exchange reaction in a water softener to remove calcium from hard water.
Calcium hydroxide is used to test for carbon dioxide because the product of the reaction, calcium carbonate, is insoluble, and easily visible.
The best way to answer this question is with an example. Using Calcium oxide reacting with hydrochloric acid, the reaction formula is: CaO + 2HCl ----->CaCl2 + H2O The molecular weight for Calcium Oxide is 56, for Hydrochloric acid is 26.5 and for calcium chloride 110. If you start with only 56g of Calcium oxide but say 10000g of hydrochloric acid, the maximum yield of the product calcium chloride can only ever be 110g. It does not matter how much hydrochloric acid is added. The limiting reactant in this example is the calcium oxide.
Can I answer with a question? How is calcium hydroxide formed? What is "lime water"
This depends on the reaction involved.

It may be either a reactant or a product depending on what the reaction is. If you react elemental zinc with sulfuric acid to form zinc sulfate and hydrogen, then it is a product. If you react aqueous zinc sulfate with sodium hydroxide to form solid zinc hydroxide and sodium sulfate, then it is a reactant.
The solubility product (Ksp) of calcium hydroxide is approximately 5.5 x 10^(-6) at 25°C. This value represents the equilibrium constant for the dissociation of calcium hydroxide into calcium ions and hydroxide ions in a saturated solution.

Sodium nitrate can be both a reactant and a product, depending on the reaction. It is commonly used as a reactant in the production of fertilizers, explosives, and other chemicals. It can also be a product of reactions involving sodium hydroxide and nitric acid.

To determine the limiting reactant, calculate the moles of each reactant using their molar masses. Then, use the stoichiometry of the reaction to determine which reactant will be consumed first. Whichever reactant produces the lesser amount of product will be the limiting reactant.
The reaction between carbonic acid and calcium hydroxide forms salt (calcium carbonate) and water as the other product.
