I am debating between getting a 2020 or a 2021 model. I realize I will have to wait a little while yet for the 2021 model but if it is worth it, I will. 

Anyways, I was reading about the 2020 models having noisy engines. I know this can be a general complaint that most people don't care about but I don't want a loud car. Our garage is attached to the house so I don't want to wake up my wife or our kids when I am out later in the evening and I don't want to leave it out of the garage. Sounds silly, I know but a loud engine is a deal breaker for me.

Most budget vehicles (ones under 35k) will be louder than pricer ones. I never had an issue the nose level in any corollas I have owned. A work friend of mine has the 2020 model and it seems quiet to me the few times I have been in his car.
