All Google Ads non-last click models, which includes data-driven attribution, has been upgraded to support both Display ads and YouTube. The data-driven attribution model now also measures engaged views from YouTube.
The advantage these upgrades bring to the table is the data-driven attribution model will learn more from how users interact with ads and convert. If you use this new feature along with automated bidding strategies or updates to your manual bidding, data-driven attribution will help you drive even more conversions at the CPA compared to the last click.
