190 degree water to a kitchen faucet would be a bit crazy.
And the instant hot is only good for a few cups of hot water. It's not going to wash a sink full of dishes.
The recirc makes the most sense. They make a remote system that will fit under the kitchen sink, or you can install one at the water heater.
Putting a small remote water heater at the kitchen sink would mean running power there too. They also have relief lines that need to be drained. Way too much work, and most of those are just six gallons. Still pretty small for a kitchen.
