Beginners usually do not need every tool category at once. They need a stack that covers the most common production hand-offs cleanly.
Start with the roles
One tool for strong still-image ideation. One tool for motion or sequence generation. One editor. One voice or sound layer. That is enough to learn the system.
Choose for clarity, not for volume
Too many subscriptions usually hide the fact that the workflow itself is still unclear. A smaller stack forces better decisions.
Test tools against the same scene
The fastest way to understand value is to compare outputs for the same shot brief, then judge which tool gives you more control and less cleanup.
