RadioRA 3, 240V Car Lift, and Garage Door Opener - Best Practices to Kill Power to Garage Door when Lift is in Use?

I'm updating our garage to install a car lift, and am getting paranoid about someone opening the garage while a car is up in the air. I have an opportunity to do whatever wiring or equipment is required, as we'll be pulling a new 100-125A panel into the garage.

I had planned to do the following:

• Install a dedicated 20A 120V outlet for the wall mount garage door opener
• Install a NEMA 6-20R 240V outlet; I had hoped to use this for both table saw operation and the car lift by simply unplugging one or the other

I'm now thinking that I should revise the plan as follows:

• Install a dedicated switched 20A 120V outlet for the wall mount garage door opener, tied to an RRST-8ANS
• Install an Infratech Contactor Panel to the 240V outlet, tied to an RRST-8ANS for switched power
• Configure both switches in Lutron Designer to toggle the other when used, so only one can be powered at any given time
• (If I need an always-on 240V for other equipment I'm likely going to install a separate one)

I'm mostly concerned that the 8ANS is not nearly the same amperage as a dedicated 20A, and I'm reading mixed reports on amperage requirements for garage doors. Is there another option here, or could I leverage the Contactor Panel for the 20A outlet as well?

Thanks for any feedback!
