Newly built single-family house approx. 170m² city villa

What kind of houses and properties do you have that you have to carry your shopping 40 meters? I had that before in Augsburg where the parking lot was somewhere else.

House about 10 x 10 meters, the garage is set back and the entrance is at the front. Usually, you don’t just have one shopping bag. Plus the cases of drinks. You can easily get 40-50 meters together. The problem is solved with a simple door.

Three friends have a direct passage from the garage to the utility room and wouldn’t give it up anymore.

Don’t build for your friends, build for yourself.
If it works out and the design doesn’t suffer any disadvantages, then build it that way. The house is planned with several components, so you just have to decide what to stick to or not.

If needed, just throw the dirty clothes there into the laundry.

If you can cycle directly into the garage, that would be practical. You just have to weigh your cycling a bit: to what extent are you at a disadvantage if you can’t do it that way? And can you even cycle past your car (in the garage, mind you)? Is there space to unload? Would the door be open? Do you have to open it first, then the front door would probably be faster, more practical, and the utility room wouldn’t be far to reach above the hallway.
And not only with an open garage, a burglary-proof door is needed as an intermediate door.
If you then pack your worn clothes along with the washed laundry, you can choose which other door you use half-naked to get upstairs,

that you don’t have to carry 40-50 m

The problem is solved with a simple door.

I would say, in this case, the problem does not exist with the right garage and house planning.

With multiple bags, I park in front of the front door and not in the garage.

Which drinks or food items are stored in the warmest room between the dirty laundry and the ventilation system?

A door is practical, I have one myself, but not essential, especially not if you limit yourself with placement, etc., or regenerate a large paved area.

And then you move the car again afterwards? Hmm, for me that's a strange idea. If possible, I would try to avoid that.

As an adjoining room, we have a pantry. I wouldn’t store food in the utility room either.

sorry, but how often does it happen? Maybe once a week? That’s acceptable for me.

It depends on how forgetful you are... It is acceptable. For me, it is also acceptable to walk 100-200 m. Whether one wants to or not, everyone has to decide for themselves. Access to the house is not the be-all and end-all for me, but if it can be realized, I would do it.
