I use a fruity Olive oil in salad dressings, a more pungent, grassy oil as a finishing oil, and a more bitter finish oil for dipping. But that's just my taste.
As for solidifying in the fridge, this is from an article on same, from the question and answer, as to why fridge test is not reliable.
Paul: No, you can’t. Some olive oils can have as little as 55% monounsaturated fat, and lots of linoleic acid (a polyunsaturated fat), similar to soybean oil: olive oils made from the Arbequina (a popular one for California oils), Chemlali, or Chétoui cultivars (the later two being the dominant ones in Tunisia) are especially prone to low monounsaturated fat levels. Unless they also have a lot of waxes, these oils probably wouldn’t freeze up. And a friend of mine in the olive oil business recently did an experiment where she put a very high-oleic-acid (83%) oil into the fridge, and it didn’t freeze up, for reasons not known: maybe the very low level of saturates, maybe a very low level
Olive oil is a natural product, made from >700 different varieties of olives, each with their own characteristics, grown under different conditions, picked at different levels of ripeness, and processed differently. There are just too many variables affecting waxes, fatty acid ratios, and the distribution of these into triglyceride structure to make the fridge test reliable as a positive or negative screen for authenticity (let alone quality).
