Answer 1

You can simply:

$('.filter-select').each(function() {
        const allData = $(this).data();
        $(this).on('change', function() {
            // use allData to access all
        })

    })

Answer 2

Instead of using each, and then trying to attach event listeners to each .filter-select element use event delegation to attach a listener to a parent element so that it captures the change events from all the .filter-select elements as they "bubble up" the DOM.

$(document).on('change', '.filter-selector', handleChange);

function handleChange() {
  console.log($(this).data());
}

  <option selected>Choose (id: 1)</option>
  <option value="1">1</option>
  <option value="2">2</option>
</select>
<select data-id="2" class="filter-selector">
  <option selected>Choose (id: 2)</option>
  <option value="1">1</option>
  <option value="2">2</option>
</select>
