I would do it like this, create an apex class to retrieve the picklist values, (You can't use SelectOption because it's not aura enabled so using a basic map, you could also create a wrapper class), create a javascript controller to put the data in the right attribute. 

public class RetrievePicklistValuesController {
    
    @AuraEnabled
    public static List<Map<String,String>> RetrievePicklistValues(){
        
        List<Map<String,String>> IndustriesPicklistValues = new List<Map<String,String>>();
        
        Schema.DescribeFieldResult fieldResult = Account.Industry.getDescribe();
        
        List<Schema.PicklistEntry> picklistEntries = fieldResult.getPicklistValues();
        
        for( Schema.PicklistEntry entry : picklistEntries){
            IndustriesPicklistValues.add(new Map<String, String>{'value' => entry.getValue(), 'label' => entry.getLabel()});
        }       
        return IndustriesPicklistValues;
    }
}

<aura:component implements="forceCommunity:availableForAllPageTypes" access="global" controller="RetrievePicklistValuesController">
<aura:attribute name="listOptions" type="List" default="world"/>

    <aura:handler name="init" value="{!this}" action="{!c.doInit}"/>
    
    <aura:iteration items="{!v.listOptions}" var="item">
        <ul>
            <li>{!item.label} - {!item.value}</li>
        </ul>
    </aura:iteration>
</aura:component>

({
    doInit : function(cmp) {
        var action = cmp.get("c.RetrievePicklistValues");
        
        action.setCallback(this, function(response) {
            var state = response.getState();
            if (state === "SUCCESS") {
                cmp.set('v.listOptions', response.getReturnValue() );
            }
        });
        $A.enqueueAction(action);
    }
})
