All Praise to Allah Subhan o Taala and blessings on Prophet Muhammad peace be upon him His Family and Companions
As you have asked for the Ahadith regarding specialities in people standing in first rows of Salah so here are some about specialities and Virtues
Abu Mas'ud (May Allah be pleased with him) reported: The Messenger of
Allah (ﷺ) used to gently pat our shoulders when we were standing in
rows at the time of Salat and say, "Keep (the rows) straight; do not
differ from each other lest your hearts should suffer from discord.
Let those of you who are mature and prudent (wise) be nearer to me, and
then those who are next to them."
And About Best of rows for Men and Women
Abu Hurairah (May Allah be pleased with him) reported: The Messenger
of Allah (ﷺ) said, "The best of the men's rows (in Salat) is the first
row and the worst is the last; but the best of the woman's row is the
last and the worst of their rows is the first."
About Virtue for being in the first Row
Narrated Abu Huraira: Allah's Messenger (ﷺ) said, "If the people knew
what is the reward of making the call (for the prayer) and (of being
in) the first row (in the prayer), and if they found no other way to
get this privilege except by casting lots, they would certainly cast
lots for it. If they knew the reward of the noon prayer, they would
race for it, and if they knew the reward of the morning (i.e. Fajr)
and `Isha prayers, they would present themselves for the prayer even
if they had to crawl to reach there.(Bukhari)
Al-Nu’man b. Bashir said: the prophet (ﷺ) used to straighten us in the
rows of prayer as the arrow is straightened, until he thought that we
had learned it from him and understood it. One day he turned towards
us, and shoulders in order, and say; Do not be irregular. And he would
say: Allah and his Angels bless those who near the first rows.(Sunan
Allah Swt and His Messenger knows best.
