I've noticed the same problems. Apparently it is possible to write a program that will keep the laptop from sleeping if the lid is closed. (https://www.appducate.com/2012/12/keep-laptop-awake-even-when-lid-closed/ https://www.appducate.com/2012/12/keep-laptop-awake-even-whe... is one I found, but I haven't tried it.) Given that, I wonder if it is possible to write another program that will check to see if a time machine backup is running, and keep it from sleeping until the backup is completed, after which it will sleep.
