I would agree that often Spanish ATC is not great and sometimes outright dangerous.
However, maybe you could have dealt differetly with the situations you describe? Instead of assuming (never good), confirm that your cleared altitude will keep you save.
Ask for approach clearance or at least the expected ILS way before crossing the parallel approach.
Just listen on the tower frequncy for the current winds. Every t/O clearance comes with a wind check and most if not all aircraft/operators are limited to 10 knots tail wind just like you guys.
Not saying all is well in Spain just giving you some ideas of how to stay safe and minimize frustrations. You will see that this will help a great deal when you transfer to a long haul fleet and fly (far) beyond Europe.
