I put whatever leftovers in there. Pasta, chicken and rice, soups, BBQ, doesn't matter. I lightly cover it. Press Reheat. Perfect every time. I don't have to judge how much to turn two knobs.
Same goes for potatoes. Stab it with a fork a few times, butter and salt the outside, toss them in and press "Potato". Perfect baked potato every time.
Same goes for steaming veggies. Frozen or fresh, doesn't matter. Toss them in a bowl, put a bit of water/butter/seasonings in it, lightly cover, press Vegetable, and boom perfectly steamed veggies.
The one-touch sensor modes on my microwave are fantastic. And this is a 20-year-old microwave, so it's not like adding this tech made it less reliable. I'll be sad if I ever need to have a different microwave.
I've only ever left the how high on high, and the time is 3 minutes for chilled, 10 for frozen. so in a way I agree, two buttons saying chilled and frozen would also work for me.
I've used a number of microwaves with these modes which asked for a weight. Those were pretty untrustworthy on their results, because moisture content and starting temp can vary greatly.
I stumbled upon them, but I strongly think the mid-2000's era GE Profile are probably some of the best appliances ever made. They were at least the best dishwasher, oven, and microwave I've ever used.
A few years later all microwaves had chiclet keypads with terrible user interfaces. They’ve improved from there over the years but never to the convenience of the original knob layout.
