Is it possible to just fill the shipping address fields with my own values?

For example, I want city field to be filled with "My City" when an event occurs on the checkout page. I know the checkout page uses Knockout JS, but I haven't figured out how to pass values to the fields themselves.

So far, I have jQuery running on the checkout page but writing code:

$('input[name="shippingAddress.city"]').val("My city");

but this does not seem to work.

Yes, It is possible. It works fine in my case.

require(['jquery'], function($){

    var onDomIsRendered = function(domString) {
          return new Promise(function(resolve, reject) {
            function waitUntil() {
              setTimeout(function() {
                if($(domString).length > 0){
                }else {
              }, 4000);
            //start the loop

            $('[name="city"]').val('My city');

Because Shipping address from update value by event keyup so you can try:

$('input[name="shippingAddress.city"]').val("My city").keyup();
