Welcome! Yours is an interesting situation. Without a garage, you will have to get an outdoor rated EVSE (charger), so that will cost a bit more. Of course, free charging at work for 8 hours could be enough that you never need to charge at home. One consideration is how much you drive on the non-work days, when you aren't charging at work. And how far might you drive on those non-work days.
I've had my PHEV for just over 3 months, and if Kia offered me a no cost trade (just a higher payment) on my lease to switch to the e-Niro I would probably jump on it. The PHEV has many strengths, particularly the flexibility to drive extremely long distances with just a quick stop at a gas station. And on gas alone it has a range of about 600 miles. During these warm days, I've been able to get 34 EV miles, even with the A/C on, but I would enjoy the pure EV more. The down-side to the PHEV is that the electric motor is only a little more powerful than the standard hybrid, and climbing long hills or accelerating up freeway on-ramps there isn't enough EV power to keep up with traffic, so the ICE has to start. The EV has a much more powerful motor. You cannot floor the throttle without the ICE starting, and of course when it gets cold the ICE is the only way to warm the interior.
In general the two versions are quite similar. The front grill is different on the EV, the charging port is in front instead of the left front fender, it has a knob for shifting instead of a "normal" console shifter, and it has an electronic parking brake instead of the foot pedal. One thing the EV lacks is a driver's memory seat. It does offer a power seat, but no memory positions. The PHEV does have that.
Be sure to read the post that Dovidan linked, as he has experience testing the EV, and I've only read about it.
