The best Python mini-framework to be involved with in 2021?

I have to admit that it's a long time I'm not doing anymore server-side coding and web development in that way, and by my time I was mostly stuck with the .net world.

As of these days, I've been working on a Python project, started as a joke and became a fully fledged app, which now I need to port to web. I've no time to test several (mini)frameworks and I don't mind writing few more lines of code if is needed. But the crux is which is the best mini-framework to use when some is starting from 0?

Reading this, I may have made up my mind to three choices: Flask, Pyramid and Bottle. They are in the order how I would probably go for. Ideally I need them to be "easily" deployed either on an Apache or Ngnix instance.

I wonder if I can grab your brain and understand your thoughts/preferences.

Thanks
