FIELD-LEVEL SECURITY

Enforce or bypass FLS.

USER_MODE is a default option. You can set SYSTEM_MODE for all queries by adding .systemMode() to selector class.

public inherited sharing class SOQL_Account extends SOSL implements SOSL.Selector {
    public static SOQL_Account query() {
        return new SOQL_Account();
    }

    private SOQL_Account() {
        super(Account.SObjectType);
        with(Account.Id, Account.Name)
            .systemMode(); //default FLS mode
    }
}

public with sharing class MyController {

    public static List<Account> getAccountInSystemMode() {
        return SOQL_Account.query().toList();
    }
}
