When using Voice Control, say: "Show names". You'll see all the accessibility labels for interactive elements overlaid on the screen. It will help you identify labels that can be improved, or actually missing. Labels are not just for VoiceOver.

Have you ever seen VoiceOver randomly focusing on elements of the previous view when presenting a custom modal view? That can be fixed by letting the system know that the presented view is modal in terms of accessibility.
Custom actions work with VoiceOver, Switch Control and Full Keyboard Access. They also do for Voice Control. You can say "Show actions for <item name/number>", and an action sheet with all options, numbered, will be presented to the user. For some use-cases, Voice Control users might not feel it is a big win. Navigation is not as big of an issue, and interacting with custom actions might be a bit trickier than with "exposed" buttons. But lots of times seems a fair compromise.
One of the accessibility issues I see more often in iOS apps, believe it or not, is unlabelled elements. This happens especially for buttons with an icon but no title. In those cases, you need to configure an accessibility label manually.
