Below is a class to get all picklists and their values for an object, but I feel like there must be a more efficient way to do it. The main question is, given the name of the object as a string property, do I have to create list<Schema.SObjectType> gd = Schema.getGlobalDescribe().Values() and then loop through all items in the list until I get to the object I want? Or is there a better way to do go directly to the one I want?

public class GetPicklistsForObject {

  public string theObjectType {get; set;} //the object we're going to get the picklists for
    
  public List<cObjects> getMyPicklist() {
    
    list<Schema.SObjectType> gd = Schema.getGlobalDescribe().Values(); 
    list<cObjects> myobjects = new list<cObjects>();  

    for(Schema.SObjectType f : gd) { //for all objects in the schema

       if (f.getDescribe().getLabel() == theObjectType) { //we've found the one we're looking for
         
            Map<String, Schema.SObjectField> theFieldmap = f.getDescribe().fields.getMap(); //field map for object
            
            for(String field: theFieldmap.keyset()){ //for each field in the object
              
                   Schema.DisplayType theResult = theFieldmap.get(field).getDescribe().GetType(); //get field type
