What you need before you start

The fee has a base fee and a priority fee. The base fee changes with demand and is burned under EIP-1559, so the final total can differ from the estimate.
Yes. A public block explorer shows current gas fees and the mempool without a wallet connection.
A low priority fee can leave your transaction in the mempool until a block proposer selects it. Some wallets let you replace it with a higher fee to speed it up or cancel it.
No. Layer 2 networks run on top of Ethereum and have their own fee markets. Check their fees on their own explorers.
