You can use .day(n), and then just combine it with .startOf('month') to do this.

This method can be used to set the day of the week, with Sunday as 0 and Saturday as 6.

If the value given is from 0 to 6, the resulting date will be within the current (Sunday-to-Saturday) week.

If the range is exceeded, it will bubble up to other weeks.

Demo:

const days = {
    Mon: 1,
    Tue: 2,
    Wed: 3,
    Thu: 4,
    Fri: 5,
    Sat: 6,
    Sun: 7
}
const nthDayOfMonth = (monthMoment, day, weekNumber) => {
  let m = monthMoment.clone()
   .startOf('month')                     // go to the beginning of the month
   .day(day)
  if (m.month() !== monthMoment.month()) m.add(7, 'd');
  return m.add(7 * (weekNumber - 1), 'd').format('dddd YYYY-MM-DD')
}

console.log({
  firstSaturdayThisMonth: nthDayOfMonth(moment(), days.Sat, 1),
  firstSundayThisMonth: nthDayOfMonth(moment(), days.Sun, 1),
  firstMondayThisMonth: nthDayOfMonth(moment(), days.Mon, 1),
  firstTuesdayThisMonth: nthDayOfMonth(moment(), days.Tue, 1),
  firstWednesdayThisMonth: nthDayOfMonth(moment(), days.Wed, 1),
  firstThursdayThisMonth: nthDayOfMonth(moment(), days.Thu, 1),
  firstFridayThisMonth: nthDayOfMonth(moment(), days.Fri, 1),
  secondSaturdayThisMonth: nthDayOfMonth(moment(), days.Sat, 2),
  secondSundayThisMonth: nthDayOfMonth(moment(), days.Sun, 2),
  secondMondayThisMonth: nthDayOfMonth(moment(), days.Mon, 2),
  secondTuesdayThisMonth: nthDayOfMonth(moment(), days.Tue, 2),
  secondWednesdayThisMonth: nthDayOfMonth(moment(), days.Wed, 2),
  secondThursdayThisMonth: nthDayOfMonth(moment(), days.Thu, 2),
  secondFridayThisMonth: nthDayOfMonth(moment(), days.Fri, 2),
  secondTuedayMarch2020: nthDayOfMonth(moment('2020-03-15'), days.Tue, 2),
  thirdFridayDecember1986: nthDayOfMonth(moment('1986-12-04'), days.Fri, 3)
})
