At a minimum BF owes you a duty of care to include hotel, food, and local transport. If the reason for the cancellation is not an "extraordinary circumstance" you are also entitled to delay compensation of EUR 600.

Finally, at your option, you may cancel your ticket for a full refund and then purchase whatever you want. Some argue that BF must rebook you on other carriers, but there is no holding to that effect. I would look up other more convenient flights and ask.
