SEC has not approved Bitcoin ETFs [fixed] 3 years ago
Not all transactions have multiple outputs as some deplete the UTXO with no remainder. The 2 single output transactions you mentioned are Bitcoin NFT mints. Their senders only care about including their data in a bitcoin block, they don't really care about the small value of the UTXO output being sent, that's why the overwhelming portion of transaction value is just miner fees.
The 3rd transaction you included is an ordinary bitcoin transaction that sends value.
