Welcome to the forums ! I would definitely go with the power steering just because of the ease of use. Too much effort especially for the wife if she'll be using it.
I am in similar situation. I just wanted the digital display/odometer etc. Didn't care much about power steering but it might come handy as I ageI wasn't going to buy the power steering option but It was the only way to get the other options I wanted. So EPS is what I got and it is pretty nice. If I was going to do it all over again I would buy it with power steering again without a doubt.
