I practiced a similar question where direct writes to GCS were suggested, but I wonder if that would handle the volume efficiently.

I'm not entirely sure, but I feel like streaming data directly to BigQuery could be too heavy for real-time ingestion.

I remember we discussed the importance of scalability in data ingestion. I think using Google Cloud Pub/Sub might be the best option here.
