@akgt In my tests, WP Fastest Cache performed very well. I would recommend using it for page caching. Everything else can be enabled in Asset CleanUp. LiteSpeed cache also performed well, though it’s more complex than WP Fastest Cache and you have to be careful not to mix features. I haven’t used Docket Cache so I can’t give you any feedback about it. It’s a new plugin and I will consider doing some tests at some point in time when it grows in popularity. There were no support requests about Asset CleanUp and Docket Cache so far.
As for AutoOptimize, as far as I’m aware it lacks page caching and you will need it (unless your hosting company offers it), though you need to make sure to use a caching plugin, not just a front-end optimization one. If Autoptimize has a feature that you really want to use and Asset CleanUp doesn’t have it, then sure you can use the plugin, but be careful not to mix features such as enabling CSS/JS minify in multiple plugins.
