Hi @Mikirinne
It depends on the size of your Meetings and Webinars, and whether any need to run concurrently.
If your Meetings are under 100 Participants, and your Webinars are under 500 Attendees, and nothing will run concurrently, then all you will need is a Pro license with a Webinar 500 Add-On.

If you need something more complex, post back here with more detail, for more guidance.
Hope this helps.
