I've added three methods.

1 is Select<T>() that allows you to not pass a list of columns to be fetched.
Ex:

class Post
{
    public int Id { get; set; }
    public string Title { get; set; }
    public Date CreatedAt  { get; set; }
}

//before
new Query("Posts").Select("Id", "Title", "CreatedAt").Get<Post>();

//method I added
new Query("Posts").Select<Post>().Get<Post>();

2 and 3 are Insert<T>() and it async version InsertAsync<T>() that allows you do not pass enumerable of columns and values then you need insert many rows
Ex:

class Product
{
    public string Name { get; set; }
    public decimal Price{ get; set; }
}

//before
var cols = new [] {"Name", "Price"};

var data = new [] {
    new object[] { "A", 1000 },
    new object[] { "B", 2000 },
    new object[] { "C", 3000 },
};

db.Query("Products").Insert(cols, data);

//method I added
var data = new List<Product>()
{
    new(){ Name = "A",  Price = 1000 },
    new() { Name = "B",  Price = 2000 },
    new(){ Name = "C",  Price = 3000 }
}

db.Query("Products").Insert(data);

Select<T>() and Insert<T>() use reflection to derive property names and use them as column names

@nester-a Do you use data annotations for column and table names? https://stackoverflow.com/questions/56993920/reflect-table-column-names-based-on-data-annotation

Sometimes I use such annotation when my columns do not reflect the reality.
