I haven't read most of the other replies, because I'm not that interested in what others want in their kitchens and don't think their preferences are usually like mine (which is why I don't care what theirs are).
We remodeled our home a few years ago and I designed the kitchen (with help) and it is close to perfect (for me). Two (or more) people can work in it without crashing into each other.
The floors and counter tops are both made of tile. If I did it over, I'd get better floor tile -- the stuff we picked is treacherously slippery when wet, something I didn't realize until it was too late. The tile-topped counters cost ~$2/sq foot (we installed them ourselves). I will never again (if I can avoid it) have a kitchen where I can't put a hot pan down on the counter.
The kitchen is about 12 feet long by 9 feet wide. At one end there's an island that will seat 4 (would have seated 8 had I insisted that the builder design it the way I originally wanted, i.e., longer, but I yielded to his advice -- oops). It has cabinets underneath it that open from both sides and are used to store less-used things, mostly the "good" plates, etc.
The kitchen itself has a long, L-shaped counter. Fridge at one end, on the leftmost edge of the long-L. I am right handed. Immediately next to the fridge, a 3' (approx.) length of butcher-block counter. Under that sits a board the same size as the counter that is about 6 inches lower than the counter and that can be pulled out (it is as deep as the counter is and can be pulled out to that depth). This offers both a work area that someone seated (e.g. in a wheelchair) or short (e.g. a kid) can work at, and a readily available, flat, uncluttered surface right next to the fridge where bags of groceries can be placed for unpacking. It is divine. Underneath it are drawers I use for storing food storage containers and food prep tools. The pots-n-pans also hang from a metal-mounted ceiling rack above this, though ideally they'd be closer to the stove.
Next there's the sink with a big window in front of it, looking out over the yard, and beside that the dishwasher, then a lazy Susan (installed) piece in the corner cupboard, more counter surface in the short edge of the L and the stove.
Lower cabinets are drawers or have shelves that pull out fully (I'd probably do 100% drawers if I had it to do over). The floor of the large cabinet that sits under the sink is a drawer, so it can be pulled out -- no scrambling to reach the cleanser/garbage bags, etc. Dishwasher is installed, everything else pretty much drops into place (and can be removed). I want things DH and I can easily replace ourselves. Microwave just sits on a section of the counter (corner over the lazy susan between the sink and the stove). Stove is flat-topped glass, and yes, I'd do induction if I had it to do over. Stove controls on current unit are at the rear, if I replace it they'll be at the front (safety + universal access). Stove vents to the outside for real, doesn't just recirculate.
Drawer & cabinet fronts are flat wood with no horizontal surfaces whatsoever (except their top edge), so they don't have dust/dirt clinging to them that needs to be cleaned off. Appliances are black. My new obsession after several irritating failures is to have appliances that only have mechanical/analog (not digital/computerized) parts -- last time the dishwasher failed, the repairman told us there were 3 computerized sections of the thing, the failure was caused by one of them, he couldn't tell us which one, and we could start replacing them one at a time, cost $150 each + service call each time, until we figured out which one it was. Our new dishwasher has only knobs. It's not my favorite for function and probably loses on energy efficiency, but as compared to having to replace the stupid thing every ~5 years, I'll take it.
Other appliances are minimal -- we own a kitchen-aid mixer (sits on counter beside stove), a toaster, and a toaster oven. The toaster is only b/c DH finds the toaster oven takes too long to make toast.
I do not like to cook and increasingly take steps to embrace that reality -- I buy bacon cooked, I buy veggies frozen, chopped. I like having a functional kitchen because I don't like to cook, so I want to minimize the time/effort I spend there.
