New construction is looking for a garden planner because we are not creative enough

Ah, I read the 3 as a 7. Then the whirlpool doesn't make sense. Because the seating area with fire basket can be made drivable.

I still need trees in the system

We are missing those too. We had thought of espalier trees as a privacy screen towards the neighbor on the right.

I quickly sketched something dirty
I would place the whirlpool close to the terrace (for evenings or children during the day). Apparently, you have a water connection there in the corner?
Fire corner in the west. You could enclose and plant it with the mentioned raised beds.
Possibly plants for privacy screening… But I saw on the Reolink picture that the neighbors have already provided privacy screening? There are nicer options. Regarding the bench by the shed, I confused myself with the shed. At the corner of the terrace, a shallow bed with a tree, e.g. a maple, that doesn’t grow too big. I actually find the concrete stones quite nice. Nevertheless, you could plant two groups of shrubs there. Such beds don’t require much work.
Are those your walls in the SE? You could plant climbers there, e.g. clematis.

Plants: Plants from the “wild hedge” in the SW combined with an evergreen ball and a jasmine or elderberry. Maybe also fruit shrubs (currant or sea buckthorn) and a columnar cherry laurel as a larger evergreen plant.
Grasses by the fire bowl with hardy roses.
Beware of thirsty plants, e.g. hydrangeas, I would no longer plant them nowadays, rather prairie plants. Fire bowl on gravel.

I am a big fan of natural gardens that also give something back. I can definitely recommend naturadb for selecting plants, you can filter there! It’s best to choose native, site-adapted plants – according to your soil and sun / partial shade / shade. Then you can filter by flowering time, color, etc. and find plants for yourself.

There are native plants suitable for every area. In prairie beds, many North American plants are included, which don’t really benefit our native insect life.

Such gardens can also be designed in a modern and tidy way, depending on what you like. Lawns require a huge amount of work and are a “green desert,” useful to no animal and consuming a tremendous amount of water.

Whirlpool I would place close to the terrace (for evenings or children during the day).

Remember that a whirlpool can be quite ugly. Especially the plastic ones. At least that's what I think. I do find the suggested spot practical for it, but if it ends up being an ugly thing, then I wouldn’t want it there.

Remember that a hot tub can be really ugly. Especially the plastic ones. At least that's what I think. I do find the proposed spot practical, but if it turns out to be an ugly thing, I wouldn't want it there.

This is a sketch, quick and dirty. Meaning: an example, spontaneously scribbled on paper.
To the right of the hot tub is a rectangle - sort of a seating wall or something similar. A little imagination is allowed.
