does not work.

Answer 1

Your code does not fill in the field itself, but fills in a selection list - a list of values ​​from which the user will be able to choose if the selection mode from the list is set.
By the phrase "does not work" it is not possible to understand what the problem is: is it impossible to fill in the selection list, or is it impossible to choose from it?
In the first case, the select list needs to be filled in, not replaced with your list of values.
Something like this:
ChoiceArray = Query.Execute().Upload().UnloadColumn("City");
ThisForm.FormElements.SelectCity.ChoiceList.LoadValues(ChoiceArray);

Answer 2

Look in the form field event helper syntax AtStartSelection and AtStartSelectionFromList (depends on field properties). And then StandardProcessing=false; and fill in the selection data. Do you have managed forms at all? If so, then it is better not to write queries in the context of the client
