If you don't have a business with profit in hundreds of millions of dollars a year (or revenues in billions of dollars a year with no profit), then you should just go with whatever domain and TLD you get, preferring the originals, like .com and .net, then preferring any ccTLDs, and then preferring other TLDs. I don't think many common people recognize and understand that something like .google or .amazon is really a website address. Don't worry about the TLDs that you cannot get because of the price or because it's being squatted.
If you do have a business with profit in hundreds of millions of dollars a year (or revenues in billions of dollars a year with no profit), spend a low fraction of a digit percent of it on brand management by engaging a company that can help you figure out the right mix of domain name, brand value, which squatted domain to buy, how to buy it for cheaper, etc.
