With 1 sat/vbyte, it's part of a very large pool. That's why I prefer to use 1.1 sat/vbyte instead, so at least you're above the large majority.
Chances are the transaction would have been dropped if you wouldn't have broadcasted it again.
Broadcasting isn't the same as accelerating. The only working free accelerator I know is ViaBTC, but it requires a higher fee and smaller transaction.
Any help would be appreciated given "Trust" wallets and "Core" wallets don't include unconfirmed TX in new transactions.
Are those your receiving wallets? I don't use Trust wallet, but in Bitcoin Core, I used this once:
I did CPFP with a much higher fee (which took me a while as I had to export/import the privkey first)
After this, Coin Control in Electrum can send the unconfirmed input.
