You don’t need a sitemap generator plugin for the latest WordPress
Go to https://www.yourdomain.com/wp-sitemap.xml, that's the URL you use for LiteSpeed Cache's crawler sitemap URL. If you use the category excluder plugin, not posts in excluded categories from the front page will show. I removed the plugin on my other site. A full crawl of all the posts on this site would take even longer. At least with only one thread.
You might want to exclude wp-sitemap.xml from being cached as well. I excluded "wp-sitemap*.xml", no idea if the star works.
x-litespeed-cache-control: no-cache
Looks like the star works. Just run curl -I https://www.yourdomain.com/wp-sitemap.xml in Linux to see. Can't help you if you use Windows. I checked another XML file, and it isn't being cached either.
