Hi,
Thank you for purchased our theme.
1/ With exclude some categories in the latest posts on homepage - this theme already supports it, you don't need to use a plugin to do that. Please deactivate the plugin and check option for it via Customize > Homepage Options > Exclude specific categories from latest posts on Homepage.
2/ For create a blog page, I recommend you use WPBakery Page Builder plugin to do that.
You can check guide here to know how to get WPBakery Page Builder.
After that, go to Pages > Add New a page > select Template for this page is "Page VC Builder With Sidebar" or "Page VC Builder No Sidebar" > and use WPBakery to config this blog page by use element "Soledad Latest Posts" from WPBakery - and you can exclude any categories you want on blog page by use this element also.
Best Regards,
PenciDesign
