Are you using a dot com you purchased> If so, you may want to use your freesiterubix.com website to get used to Elementor.. If you haven't already, you may wish to watch some YouTube videos on how to site ti up and use it.

If you wish to delete the entire website and start over you can.
Menu Bar -> websites -> Site manager -> find your website
Look in lower right hand corner for "details" click on it.
Then scroll down and look in bottom left hand corner for "delete"
Click it.
To create a new one
Menu Bar -> websites -> Build Website -> Free website.

WordPress has some great blocks built within it without using Elementro.

you don't really have a reset button in wordpress...
there is a plugin that can restore things back to the start sort of....try wpreset plugin
do you need elementor....
they have done a lot of work on the speed of the site after installing it but you still need ot be careful what you use....
with wordpress's full site editing ( select a theme with the filter fse) you may noe need it.....depending on what you are using it for...
even landing pages can easily be constructed from the blocks....
have fun, but don't forget ot get ot at least 30 articles before you start styling your site....visitors and google is after content rather than window dressing.....
