you can add Custom CSS.

For example, elilyjay.com, add this custom css:

#secondary.widget-area { text-align: center; }

refer: https://www.wpbeginner.com/plugins/how-to-easily-add-custom-css-to-your-wordpress-site/

you need to contact hosting provider and request a site recovery (since it is deleted)

ok, I think I understand the issue now.

You want to keep WordPress in /wp but want WordPress to link to the homepage at the root?

In that case, you need to keep Site address to include the /wp directory. Then, make custom link at WordPress pages to link to your homepage.

Please optimise your image for web (save for web) before upload. 11MB for 2000×2000 is too large for web display.

The image uplooad process easily timeout because takes too long time to upload 11MB file.

Also, try to turn off other image processing plugin if any.

there are many ways to change URL, read https://wordpress.org/support/article/changing-the-site-url/

your .htaccess file is not the default WordPress version.
no, you don’t need to make changes to Apache config.
Make sure you have enabled mod_rewrite in apache.

have you setup permalink?
