What is the best Btc accelerator sites?
Viabtc is very good , but $86 to accelarate a transaction.

I would say that your best bet is to ask miner or a group of miners to include your transaction in their block but probably they'll charge you a lot and you'll spend some time to find them. Still the best option for you is probably to wait until it gets confirmed.
Personally I did a transaction with 4sat/B today and it got confirmed in 1 hour. What was your fee? I think you can relax.

To add to the previous 2 posts: there's a scenario I can think of in which you can't do CPFP or RBF: if you received a transaction from a third party on an exchange. But that's something you shouldn't really do in the first place.

That's exactly what I wanted to write right now. But I have noticed that some exchanges send transaction with enabled RBF feature. In this case, probably the best idea is to contact that third party to increase the transaction fee or if someone still wants or has to use third party, it's the best to avoid Bitcoin transaction in this case because these exchanges always send with very low fee and instead, one should choose Ripple or Nano or probably Bitcoin cash or Litecoin, depends how limited he is to options.
