Why did Shakespeare most likely decide to write a play based on the story of Romeo and Juliet?

Shakespeare’s version of Romeo and Juliet was first performed in the 1590s, but his adapted tale was not even close to the first of its kind.
Published in the year 8 CE, “Metamorphoses” by Ovid includes the tale of ill-fated lovers Pyramus and Thisbe. Much like the titular characters of Shakespeare’s play, this pair of lovers ultimately commits suicide because of a mistaken assumption of one’s death.
The popularity of this story endured in Boccacio’s “Decameron” and even in a lesser-known Chaucer work. Italian writers in the late 15th century and early 16th century drew inspiration from the classic tragedy of Pyramus and Thisbe and wrote the earliest versions of “Romeo and Juliet.” Shakespeare was directly inspired by Arthur Brooke’s translation of an earlier Italian Romeo and Juliet piece—a poem titled “The Tragical History of Romeus and Juliet,” published in 1592.
Therefore, Shakespeare was indirectly inspired by an ancient Roman poet, albeit through various retellings of the original tragic lovers.
