Running leggings : commando for thick leggings (or if you are particularly well endowed and need support) and seamless boxer briefs for thin, summer leggings. Example: https://www.uniqlo.com/us/en/products/E456710-000/00?colorDisplayCode=03&sizeDisplayCode=005

(Padded) Cycling leggings : they are designed to be worn without anything underneath. More fabric = more friction = irritations. The pad should do contact with your skin. If it's too revealing to your taste then yes, add something over it. But consider you are going to be seated on your bike 95% of the time so there will be little to reveal anyway. :)
