If you wish to fly in international J / domestic F as you were booked, you are free to ask AA to rebook you for the next available service which has that available. That may be 1-2 extra days in AMS, but it is your choice. Hopefully this will not happen again, but if it does, you should have the reroute you wish researched and in hand for the agent.
Alternatively, you are due a refund of the mileage difference for the ticket booked and the ticket flown. As you have not provided the full routing, e.g. "home" rather than a specific airport, it is hard to figure out. Chances are that there will not be any mileage difference.
There is an argument that you are due EC 261/2004 reimbursement for the two downgraded segments. That would amount to 75% of the segment base fare for the segment in question. Again, that might be 0 or very little.
Depending on the reason for the cancellation, you may be due EUR 600 in cancellation compensation.
If you provide your entire routing both before and after as well as the reason for the cancellation, there will be better information available.
