Since oil made from "first cold pressing" of naturally oily foods (such as olives) can be obtained without the use of chemical solvents and/or heat processes that break down the oils and accelerate rancidity, you can say they are healthier. They are also more expensive.
Since all oils go rancid through exposure to oxygen, light, and heat, and since going rancid makes them very unhealthy for you, the more fresh and local your source of oil, the better. If you want your oil as free of plasticizers as possible, buy it in glass bottles.
Refrigeration will slow further rancidification once you get it home, but most if not all oil you can buy in the supermarket is probably in one stage or another of rancidity, and eating rancid fats and oils is harmful to health.
Saturated fats like shortening and lard are more stable and do not go rancid as quickly, but it is difficult to obtain quality organic leaf lard, and shortening is hydrogenated chemically.
So your choices in the supermarket are liquid oils that are either extracted using solvents and heat, or cold-pressed oils that may be more healthy, but which have not been kept in cool dark storage, or else solid fats such as low-quality hydrogenated lard and artificially hydrogenated shortening.
If you have access to locally produced, cold-pressed oil, that would be a healthier option than the others listed above. Some surprising cold-pressed oils include oil of Mustard Seed (flavorful and not peppery as one might expect) and nut oils such as walnut oil, local peanut oil, almond oil, or if you live in the tropics, coconut oil.
Organic cold-pressed coconut oil is widely available in most places regardless of locality, and is very resistant to rancidity, and does not need chemical or heat extraction nor the addition of things to keep it from going rancid quickly, so would be a healthy choice if fresh local cold-pressed oils are not available or affordable. Coconut oil also contains many beneficial substances such as lauric acid, a fatty acid also found in human breastmilk, and medium chain triglycerides.

Cooking always leaches some of the nutrients of any vegetable. The longer a vegetable is cooked the more nutrients are leached into the cooking water. In that "raw" has the benefit of supplying all of the nutrients available in all vegetables it is better.

Is canola oil considered vegetable oil?
"Cooking oil" is actually a broad term for purified fat derived from plants which is normally liquid at room temperature. "Vegetable oil," when used to label a cooking oil product may refer to a specific oil like rapeseed oil or to a blend of different oils. Not all vegetable oils are edible - some are useful only as fuel oils. Not all cooking oils are vegetable oils - for example there are several nut oils and oils from gourds and melons that can be used in cooking. The non-vegetable cooking oils are seldom used in baking, so for the purposes of baking, the terms cooking oil and vegetable oil are pretty much interchangeable. Any recipe that calls for one can use the other interchangeably with the caveat that some oils are lower fat than others and some of them are more tolerant to heat than others. Olive oil can be substituted for cooking oil, but it changes the flavor a little bit.
