Yes i'm a newbe, i have the template that came with Concrete5 but i need to delete block holder so that i can have a clean home page (0 content) also how do i size blocks so that they are edge to edge.
About your Q:
1. clean home page (0 content): You can edit or delete the blocks. If you want to delete also the areas you need to do this by edit the code (This is not to much practical).
In my opinion because you are new its easy to change the layout by markup--> delete enableGridContainer-->add class="container-fluid":
//new my-theme/default.php after del enableGridContainer and add container-fluid class
<?phpdefined('C5_EXECUTE') or die("Access Denied.");$this->inc('elements/header.php');?>
<main class="container-fluid">
<?php$a=new Area('Main');$a->display($c);?><?php$a=new Area('Page Footer');$a->display($c);?>
</main>
<?php$this->inc('elements/footer.php');?>

If you talk about "empty site/blank site" you can install empty site (look at step 9):

2.1. "IN GENERAL": Full width grid. Elemental uses boostrap grid (learn about boostrap grid on google).
The container set max-width (box-layout) on tablet - desktop.
Inside you root theme folder you find template - for example right_sidebar.php:
You can use this class instead:

2.2. More advanced - elemental also use "enableGridContainer"

And about fluid enableGridContainer - i dont know where this is stands:

In my opinion because you are new its easy to change the layout by markup--> delete enableGridContainer-->add class="container-fluid":
** Last thing - its better to edit this theme (dont change the core folder files):
