You need to inject the model collection factory into your constructor

protected $mymodulemodelFactory;
public function __construct(
    ....
    \[Namespace]\[Module]\Model\ResourceModel\[Entity]\CollectionFactory $mymodulemodelFactory, 
    ...
)
{
    ...
    $this->mymodulemodelFactory = $mymodulemodelFactory;
    ...
}

and you can use in any one of the class methods:

$collection = $this->mymodulemodelFactory->create();

Have you debugged what $this->_categoryFactory->create()->getCollection()->getData() gives you? Just outputting the collection data like that into a select box values field wont get you anywhere.

You need to do something like this i think:

$itemsArray = [];    
foreach($this->_categoryFactory->create()->getCollection()->getItems() as $item) {
    $itemsArray[] = $item->getName(); //or title or whatever it is
}

  $fieldset->addField(
            'category', 'select', array(
        'name' => 'category',
        'label' => __('Select Category'),
        'title' => __('Select Category'),
        'values' => $itemsArray,
        'required' => true,
            )
    );

This is a rough example. Some things might not be correct but should get you going.

You need to be using a resource model ModelFactory, rather than trying to create through the object manager.
