CPT is obvious unless you play at easier difficulties where you just stockpile wonders in your capital. In that scenario, taller tends to win as the "bonus" CPT outweights the gain of new cities. This was discussed in a different thread.
Even CpT isn't that obvious for me.
Trad can really kickstart your culture (+3 for capital, legalism) meaning more CpT early game. This can be good or bad depending on how you plan to play. Obviously, if you plan to open and fill Rationalism as soon as possible, you don't want too many SP before renaissance, but if you are playing a culture game with Piety, more SPs early allows to open peity earlier for faster temples, stronger religion and more GP to plant those sacred sites that will soon give you +3GpT&CpT.
As for wonders, with a nice starting location (marble and enough hills) and focused capital, even playing on Immortal, you can stockpile lots of them with the help of Aristocracy and religion (tested in OCC, so it's obviously a very strong Wonder focus, but still in normal games you might be able to grab a number). Some wonders are easier to get as they are rarely focused by the AI. Temple of Artemis and Mauselum of Halicarnassos (if you have the required DLC) are nice wonders relatively easy to grab. First gives you a nice growth boost, second one can give you a nice GpT boost if you have enough stone/marble. Terracota Army is rarely picked early and gives you +6CpT. Machu Picchu and Railroad era castle (forgot the name) because of mountain requirement are easier to get if your capital or anohter high prod city is close to a mountain. AI will never consider mountains within 2 tiles an incentive to settle, so cities close to mountains will often be crappy later cities.
I really think there is no clear winner. It depends on a lot of factors, most were already heavily discussed, but probably we still overlook some of them
