Answer 1

Like Joji Thomas said, checkBoxList prodices an array.
You need to change your database structure so that it supports 1-to-many relations (each $model can have multiple service_requests) if you want to save this. Unfortunately Yii is not very good at this sort of thing out of the box so you have to do a bunch of things yourself.
First you need to create a ServiceRequest ActiveRecord.
Then your $model needs to have a relation like:
public function getServiceRequests() {
return $this->hasMany(ServiceRequest::className(), ['model_id' => 'id'];
}
Then in your controller (model create action) you will need to do something like this:
foreach (Yii::$app->request->post('ServiceRequest',[]) as $data) {
$item = new ServiceRequest($data);
$model->link('serviceRequests', $item);
}
If you wanna update the checkboxes too then you need to do something similar in your model update action as well.

Answer 2

Please change checkBoxList to radioList, because when selecting multiple values service_request becomes an array. Enum type can handle only string values.

Answer 3

First change your filed datatype from enum to varchar. enum only takes a single string value.
Secondly you need to implode service_request array to string for save to db.
Use bellow code before the model save function :
$model->service_request = implode("," , $model->service_request);
$model->save();
