 * Hello, good time
   I wanted to set some settings for the images of my site so that
   it is suitable for loading on different devices or size(srcset). Please suggest
   a solution. If it is possible to do this manually, I would be grateful if you
   could guide me. Otherwise, introduce a plugin.

 * Second question: Is it important what the site webserver is to choose a cache
   plugin between Litespeed Cache and Rocket?
   Because I heard that the Rocket plugin
   is not suitable for sites that have a Lightspeed web server and should not be
   used. right?

 * Which editor are you using? Images inserted with the default block editor should
   all have srcset and sizes attributes by default. For other images on your site
   outside of post and page content, the appearance of srcset and sizes attributes
   depend on the theme or plugin responsible for the image output. For example, 
   attributes of featured images depend upon your theme.
 * Themes and plugins can make use of `wp_image_add_srcset_and_sizes()` to easily
   add desired attributes. If your images lack these attributes, I recommend asking
   through the dedicated support channel of the theme or plugin responsible for 
   the image’s output.
 * There are [plugins that can optimize images](https://wordpress.org/plugins/search/optimize+images/).
   They are mainly to convert JPEG and PNG images to WebP and AVIF, but they likely
   also include srcset and sizes attributes as part of what they do.
 * You should only use one caching scheme on any given site. Multiple caching schemes
   can work against each other and result in reduced performance.

 * Thank you for your explanation
   For the second question, I want to choose and 
   install one of these two plugins. I wanted to make sure that I choose one of 
   these two plugins, or should I choose based on the site’s web server?

 * Why not try out both and see which you like better? Give each several days to
   let it adapt to your site’s traffic, then run a page speed test using each plugin
   in turn. Performance shouldn’t be the only criteria. Also consider supporting
   features, available support from the devs, regular updates to take advantage 
   of the latest tech, security patches, etc.
