There is no such thing as a "standard transaction fee". That just means that you are either using a fixed fee (which is what looks like happened) or a fixed fee rate. Neither of those things are good, you should always use a dynamic fee rate that adjusts based upon the current network state.
The transaction fee is also dependent on the size in bytes of your transaction, not the amount being transacted. Telling us the amount being transacted (especially saying it in fiat and not Bitcoin) is useless.
The reason your transaction is still unconfirmed is because its fee rate is much too low. It only pays a fee rate of ~26 sat/byte whereas the current recommended fee rate is ~180 sat/byte according to
