Someone talk me through tracking serp features?

Search Console won't really show you this, apart from the search appearance filter for some rich results. Most rank trackers do flag features now (featured snippet, people also ask, local pack, AI overview) and whether you hold them, so check whether yours has that column. If you're checking by hand, remember features change by location and device. What you see on your laptop in incognito might not be what your customer sees on their phone.
