One common trope is the 'rekindled connection'. The two childhood friends, who may have drifted apart over the years, are suddenly thrust back into each other's lives due to the arranged marriage. Another is the 'opposites attract within familiarity'. Despite knowing each other since childhood, they discover new sides to one another that they find surprisingly appealing. Also, there's often the 'family drama' trope. The families' expectations and meddling can add a lot of tension and plot twists to the story.
Well, a really frequent trope is the 'hidden feelings' one. Since they're childhood friends, there could have been unspoken feelings all along that surface when the arranged marriage is on the table. Then there's the 'adjustment period' trope. They have to adjust to being in a romantic relationship instead of just a friendship, which can lead to some really cute and awkward moments. And don't forget about the 'external threats' trope. There might be other people interested in one or both of them, causing jealousy and more drama.
A typical trope is the 'discovery of self through the relationship'. Through the arranged marriage with their childhood friend, the characters often learn more about themselves. For example, they might realize what they truly want in a partner or in life in general. Another common one is the 'cultural clash' trope, especially if the story is set in a multicultural context. The different cultural backgrounds of the two families can bring in unique elements to the plot, like different wedding traditions or family values. There's also the 'forbidden love' aspect that can be played up, even though it's an arranged marriage, there could be some reasons within their families or society that make the union seem a bit forbidden at first.
