Background blurring could be great for eliminating distractions for your students. Students can also use it to protect their own privacy to not show things in the background when joining classes from home. Background blurring can be turned on or off multiple times during a meeting. I might start a meeting with my background blurred then unblur it to reveal something that I have written on the whiteboard behind me.
The option to disable chat could be helpful if you find that your students are abusing the chat or otherwise not using it as intended.
