<b>Q: Do I need to build scroll, outbound click, and form events myself, or does GA4 have them?</b>

A: GA4 already captures most of them for free via Enhanced Measurement.
— Admin → Data Streams → your stream → Enhanced measurement (the toggle). It auto-collects scroll (90% depth), outbound click, site search, video engagement, and file download.
— Form interactions exist too: <code>form_start</code> and <code>form_submit</code> fire automatically once toggled on.

Don't double-build these in GTM, or you'll get duplicate events. Only add custom tagging for things the toggle doesn't cover.

TL;DR: Enhanced Measurement gives you scroll, outbound, search, video, downloads, and forms automatically. Check the stream toggle before coding anything.
