Google Apps Script returns desired result in execution log, but cell in spreadsheets is empty

Answer for question 1:

However, when I run the script in a cell (highlighted in orange on the linked spreadsheet), the cell is empty, does anyone know how to fix this by any chance?

In your script, no value is returned. This is the reason of your issue. So please modify your script as follows.

function fullTimeEmployees(url) {
  var url = 'https://finance.yahoo.com/quote/WBA/profile'
  var source = UrlFetchApp.fetch(url).getContentText()
  var jsonString = source.match(/root.App.main = ([\s\S\w]+?);\n/)
  if (!jsonString || jsonString.length == 1) return;
  var data = JSON.parse(jsonString[1].trim())
  Logger.log(data.context.dispatcher.stores.QuoteSummaryStore.assetProfile.fullTimeEmployees)
  return data.context.dispatcher.stores.QuoteSummaryStore.assetProfile.fullTimeEmployees; // Added
}

Answer for question 2:

Also, does anyone know what I can change .fulltimeEmployees (at the end) to so it returns the full company name? as pictured here, highlighted in green

In this case, how about modifying as follows?

From:

data.context.dispatcher.stores.QuoteSummaryStore.assetProfile.fullTimeEmployees

To:

data.context.dispatcher.stores.QuoteSummaryStore.price.shortName
