How to check a wallet's Wrapped Ether balance on OpenSea or Etherscan?

Question

Etherscan shows transfers in and out of Ether, whereas Wrapped Ether (WETH) appears in Etherscan's ERC-20 transactions.

Etherscan readily displays the current Ether balance of a wallet at the top-left of the page, but how to see a wallet's WETH balance?

If not visible on Etherscan, is the WETH balance visible to others besides the user on OpenSea somehow?

In the contract tab, go to read contract and make a call to the balanceOf function with the address you wish to get the balance of.

In the scenario that the contract isn't an ERC-20 like WETH, but instead an open edition (multiple copy) ERC-721 NFT, how can someone extract a list of all holders of that contract/NFT, for either or?

For NFT you could iterate over the events that were emitted during the lifespan of the contract. Not sure if there is another easier way

Nothing on the Etherscan above, for the ERC-20, gives a list of holders of the fungible token?

No it's not part of the ERC-20 interface as far as I know of. You can also rely on the events to get such a list at any point in time.
