Personally, I would be scared if I needed to travel further than the EV range in the Niro EV because there is no supercharger network. I wouldn't be able to take road trips. My wife went three days without charging overnight last week and realized on her way to work she would need to stop at a supercharger to be safe and not get range anxiety. She only had a 40 mile estimated range and 30 miles of freeway to get home. There is no charging network except ChargePoint and a few smaller brands for non-Tesla EVs.
If you plan to not drive far everyday then both the PHEV and EV have their advantages: The EV will be all electric all the time and the PHEV will stay on EV mode for a short time, possibly meaning you won't have to fill up with gas nearly as often.
I would say this comes down to your preference. You can't really go wrong with either. The question is whether you really want a true EV and never have to fill up with gas, get instant torque, and pay a few grand more and miss out on memory seats.
EVs and PHEVs depreciate more than most gas cars as AcuraT said. However,Teslas hold their value 2 times better than the average gas car.
Also something to think about is your electricity rates and if you have time of use (TOU) plans. Here in CA we have special time of use electricity plans specifically for people with EVs. Charging at night costs 9 cents per kw/h and from 4pm to 9pm costs 54 cents per kw/h. Without these plans, it would be useless to own an EV as you would never get your ROI. I learned this the hard way after the first month of owning the Tesla because our electric bill was over $600.
I couldn't end this without telling you to test drive a Tesla Model 3 before your Kia purchase. There have been several posts online of people saying they were not in the market to purchase a car, and they unexpectedly driving out of the Tesla store with a new Model 3. I would describe the driving experience as otherworldly. It is such an amazing car. The only thing it is missing for you is it is not a crossover. It is pretty low to the ground, so that may be a deal breaker. It has some of the best seats I have ever sat in (many car reviewers have said the same). 12 way power seats for both front seats, so the lumbar adjuster has 4 ways of adjustment. The steering wheel tilts and telescopes by power and gets out of the way when the car is in "Easy Entry" mode. 240 miles is the base model's range. The base model also has Autopilot standard, so the car drives itself under supervision. Along with that is all the active safety features you expect. The car gets many software updates, so it always feels fresh and interesting. Cargo space is very good for a sedan because you get the frunk as well as the massive under-floor storage well in the trunk. It just feels like the future, but in a really good way. Delivery time is only 2 weeks now and their build quality problems are much less frequent. This video does a good job summarizing everything.
You can't really go wrong with either the Kias or Tesla. I just think the Tesla is a great deal at $39k before incentives. And it comes well equipped on the base model. The Kia EV is similarly priced, but with more incentives.
I would avoid the old Leaf. They have a problem with battery degradation. The old Soul EV might be good, but the range is short. I would recommend a Chevy Volt as well. GM hasn't embraced safety features much, but you may want to see if you can get a good deal on those before they are off the lots forever if they aren't already. Depreciation will be a problem with those I would guess.
A note on the Michelin Energy Saver A/S tires: I have those on my Prius and while they allow the car to get good MPG, they are pretty loud in my opinion. The amount of low rolling resistance tires on the market is kind of small, so there wasn't much I had to choose from. Tires can make or break your MPG. Again, I learned this the hard way with my first Prius.
