You must exit the page when changing values in the widget designer and publish.  This is to prevent the page from being cached with incorrect values (designer properties remain in Context).

The widgets that work in the template load the view with the shared information for all users according to the designer properties.

Widgets that have long cache support load dynamic content via ajax queries, the cached view has support for loading the required dynamic information.

The Catalog and Product Content widgets do not have any dependencies for changes in settings so if a setting is changed it is required to republish the pages, to see the changes applied.

Catalog and Product Content Get Status services cannot be marked as Read Only because modify the session values.

The Catalog (Catalog Nodes/Product List) and Product Content (Full-Main View) Widgets, load shared information about catalogs and products and with this information the page is cached, the user-specific information is loaded by AJAX request after page load.

Sitefinity pages cache is released when publishing a Page or Template. When publishing a template all related pages that are inherited from the template also release the page cache.
