Don't worry. The language has lots of support for the style you wish to work in. As for the specific data structures, I recommend setting aside your knowledge of their utility and consider carefully why they are being criticized. Then run some experiments to convince yourself of what is true. If you come to the conclusion that the criticisms make sense, then you can proceed with the knowledge that the people in question have thought about the issue and came to good decisions. This should inspire hope that they have thought about other issues as well and may have valuable insights. For the record, I concluded many years ago that some variant on arrays/vectors/whatever outperforms linked lists in most situations by a lot. (There are times when arrays/vectors/whatever can't work. But they are less common than most imagine.) And changes in hardware have made that more true over time. Trees, on the other hand, have a flexibility that lends itself to many problems that it is hard to find other structures for many use cases. But even so if performance is critical, it is worth jumping through a lot of hoops to make sure that all of the pointers that make up a tree are physically close together in memory to improve the efficiency of your caches.
