Funny you say this, using Siri to set timers when cooking was my "gateway drug" to using voice features on my phone more broadly.
For the longest time it was literally the only thing I used Siri for (cooking timers), but now I use Siri for setting reminders and other similar transactional stuff on my phone, and I use voice dictation for texts all the time in the car, and even sometimes when I'm walking in the cold and just don't want to take my gloves off..
And it works great. And it doesn't feel weird at all.
