If you can do without PTZ, the original Canary camera ticks all of the other boxes. 2-way audio, HD, easily remote viewable. Recording volume is very good. Talk-back audio is passable.

In recent months I've completely ditched my landline phone & internet at a few of my homes due to rising costs, which left me looking for a solution for my alarm systems.

I ended up abandoning the hardwire alarm systems (I still use them, but they don't call anyone now) and putting in T-Mobile hotspots ($10/mo) and Canary cameras, and they've worked quite well. They were particularly good for the hurricane, and I was able to pull up my cameras all around the state. It's also kind of slick that I can carry a Canary and T-Mobile hotspot and basically have CCTV coverage anywhere I am.
