Yes it's being delayed because of the fee, since you mentioned fee 0.00001784 BTC ($1.15) which is far too low are per the current average.
The absolute fee is meaningless, please keep the discussion on sat/vByte.
And the 8 sat/vByte OP has been using is indeed too low. Just look at
https://mempool.space/ for the current fees.
Here are some online links which claim to accelerate your transaction.
The free accelerator that indeed works needs at least 10 sat/vByte, so this transaction doesn't qualify.
But you're right with CPFP: if OP is in a hurry and he owns one of the receiving addresses, he can spend that (unconfirmed) input with significantly higher fee than the current average and he will get both transactions confirmed.
If OP is not in a hurry, he should wait until the week-end when the fees use to drop and maybe then his tx will get confirmed (last week-end they've dropped until around 5 sat/vByte).
