I use it all the time, and have been praying for the ability to do more with it. I spend a ton of time in the car, and its really useful in that context.

Also, its faster to tell Siri to remind me __________ or, create an appointment for ____ on ____ than to (unlock, find icon, tap +....)

I use it all day.

First thing in the morning: How's the weather?

In the car: Navigate to work. Play NOFX shuffled.

At work: Remind me to fix Monit on the Kafka cluster.

Before bed: Wake me up at 7am.

I guess talking to my phone is just weird for me, since I am not used to it, but I do all those things manually.

I check the weather with one touch on the home screen.

I don't need to navigate to work, because the trip is short enough and there won't be any heavy traffic.

The alarm is set to 6.30 anyways, I don't have to change it daily, so I just left the standard weekday setting.

Not hating on your use case, but I am always around people and I think I would get several odd glances, when talking to my phone like that.
