Hi @venepress-web,
To remove the Sidebar on specific page then Please go to the Post/page Editor of specific page/post then at the bottom of editor you will find settings/options for Sidebar Layout where you have to check ‘ON’ to ‘No Sidebar’.

And yes it is possible to hide footer featured post section on the specific page but main thing is you need to know the exact page-Id to hide it. Every pages have its own Page Id mentioned on body tag. As you have solved to hide category on before topic using ‘Category Id’ and we hope you can get the Page Id as well.

So to remove the Footer Featured Posts section on specific page then go to ‘Appearance > Customize > Additional CSS’ paste the below Custom CSS code.

body.page-id-351 .site-footer .featured-stories {
	display: none;
}

Here code sample is given for Page ID no: 351, Please replace the Id no: with yours Id. Like ‘page-id-12’, ‘page-id-18’ etc
If you have to hide on more than one page then the same code should be used again with the another Page Id no:
Like

body.page-id-351 .site-footer .featured-stories,
body.page-id-355 .site-footer .featured-stories {
	display: none;
}

Make sure you use comma (,) on every selector lines except for the last one. if you miss to use comma (,) on any single Selector Line then the whole code won’t work.

Thanks
