How will you feel about your guests walking through your working kitchen and into your mudroom to go to the bathroom? Will the mudroom always be neat and clean?

Why not put a closet in the u part of the stairwell?

BTW: A couple of thoughts.

That garage is not a 2 car garage if you have anything over a compact sized car. Trust me on that.

Your breakfast area is not large enough for a table unless you're planning on a small bistro type table and it's especially not large enough considering you need the walking room into the flex space.

Consider the space is 9' wide. A small dining table is 3' wide and a more standard one is 42" wide. That allows only 3' on each side of the dining table if you go with the 3' wide one and then you run the obstacle course around the table to get to the flex space.

The flex space is not a bedroom since there would be no place for guests to use a bathroom. and there is no closet.

The dining room is nice and large but it's far from the kitchen. Consider how you'll be shlepping food back and forth.

That foyer is very long at 16' and what looks to be about 7' wide. That's the size of a whole room but it's wasted space. And you'll be paying for that space for as long as your mortgage.

The mudroom goes right past part of your kitchen work zone. Now imagine a child running past just as you're taking hot food out of the oven.

And your fridge has no landing space. That's a traffic pattern there. Not a place for a fridge and oven.

I know you showed two other plans. This is not such a good one.
