1. Run a full node transaction
It is confusing. Running a full node to verify blocks and transactions from other nodes (peers) on Bitcoin network. You can run a full node without making any of your transactions with your full node.
Run a full node, it's not run a full node transaction. You run a full node, and if you want to make a transaction, you broadcast it with your full node.
