While YCBM does not (yet?) support auto-create of Google Meet meetings, it can auto-create Zoom meetings:

In fact, this is a feature I use very heavily, and that I appreciate a lot: I connected my University Zoom account, and all my meetings now come with a protected Zoom link that YCBM generates and hides behind a proxy so it does not get Zoombombed. The link is sent in an email an hour before the meeting to the user, and is also present in the calendar event, you can read more about that here:
I highly suggest you give it a try, it is a very seamless experience.
I completely agree with you that it does not make sense to have YCBM automate 85% of the booking process, but still have systematically to create the video conference link by hand. If you don’t strongly prefer Google Meet, I suggest you give YCBM + Zoom a try!
Good luck!
