Wonders

Borobudur

This new religious Wonder lets you go on a sudden explosion of conversion inside your borders or beyond! Be careful not to anger too many rival civilizations by converting cities away from religions that they've founded, but otherwise go ahead and shift the balance on belief in your favor. Make sure that all of your cities are believers, convert local City-States, and then eye more risky prizes.

Broadway

Broadway is a strong Culture Victory Wonder. It's not Cultural enough to be hugely important on Culture defense, so this is mostly a Wonder for people who are trying to win via Tourism. The Great Musician can be immediately turned into a Great Work of Music here, or you can send them off on a Concert Tour if you need more of a burst of influence against a specific nation.

Globe Theatre

Give yourself a burst of Cultural power with the Globe Theatre. This Wonder comes early, compared with many of the Tourism/Culture-based Wonders that are new to this expansion. Getting this lets you get started way ahead of your rivals with a little bit of Tourism, by making a Great Work of Writing. If you build the Globe Theatre simply to deny someone else its function, then use the Great Writer defensively, by writing a Political Treatise. That helps your nation resist the lure of another Cultural power.

Parthenon

The Parthenon is the earliest of all the new Culture Wonders. You won't get too much Tourism out of it, but the advantage of having a free Great Work of Art for the majority of the game is cumulative. By the time the Culture wars start in earnest, you're the one who's going to have a leg up. In addition, four Culture per turn isn't bad when we're talking about the earlier stages of the game. The Parthenon makes a noticeable difference in acquiring Policies for your young nation. Thus, it's a decent Wonder for multiple styles of play.

Prora

Prora is a Wonder to help counter the logistic difficulty in taking over the world. Autocratic civilizations often deal with great Unhappiness in the later game as their armies take city after city. You can't get Courthouses and other helpful buildings in place without a bit of time, and a successful war sometimes outstrips your ability to build (or even purchase) buildings that calm the populace.

Prora gives you a free Policy and plenty of bonus Happiness to help with the matter. Not only is it useful for Autocratic powers, but they have less competition to build it! Because this Wonder is reserved for Autocrats, it's less common for other nations to beat you to this Wonder.

Red Fort

This defensive Wonder makes your nation much harder to siege successfully. It's quite useful if you're playing against more aggressive rivals that are trying to take you over. As a conqueror, it's still useful to go after the Red Fort—not only does this protect you from other armies, but it's also nice to deny your victims any protection. Much like the Great Wall, you don't really want to face a superior defender at any time during your conquest.

The Red Fort is best constructed in a city that is already defensive; the bonus 12 Defense makes hilltop cities with defensive buildings into a nightmare. Toss a ranged unit there and laugh at anyone who comes calling.

Uffizi

The Uffizi joins Broadway and the Globe Theatre as Wonders that act as super Culture buildings. They give you plenty of slots to house Great Works, give you a Free Great Person to use as you wish, and are all used primarily by players who want to win via Culture Victories (Tourism).
