The difference is that a bulk ingest runs via COPY, which can't do a fancy upsert, but is instead optimized to just throw data into the database as fast as possible. While a regular insert uses bind parameters, which requires a database roundtrip for every single row. I would say a temporary table is reasonable for your use case.

Yes and yes: we use the COPY statement with binary format, and we use libpq as the underlying client library.

Just to clarify, the "COPY" you are referring to, is it the COPY command of Postgres wire protocol or is it something else? And is it called/implemented in adbc_driver_postgres via libpq library?
