A tempation might be for lots of pots and climbers. But this would create a lot of work in terms of watering and tending.
So I would stick to a simple, low maintenance design that will give year-round seasonal interest and impact without too much effort. For this I would look to develop the hard landscaping in a way that can be enhanced and added to over time.
I've uploaded a design, and asked AI to generate a design plan from it (I've uploaded them both to give a clearer idea).
Three large planting beds for three lots of watering, instead of many smaller pots. It will also create a semi enclosed area for the seating, as well as a privacy screen that hides the bins. The screen can be attached to the top planter. The planters will also provide interesting vista from the house.
For planting schemes in the planters I would stick to a limited palette of plants that will look good throughout the year..plants that have low water and tending requirements once established and wont outgrow the planters..
For a sunny aspect:
Choysia ternata white dazzler (for year round greenery and spring blossom);
Geranium Rozanne, Geranium Dreamland and Geranuim Biolova (for a lilac, pink and white combination). Perhaps Liriope muscari (lilyturf) if sufficient space. Spring bulbs.
For a shadier aspect:
Mahonia eurybrachteata Soft Caress (for year round greenery with winter flowers); plus the same geraniums as before and the lilyturf. Spring bulbs.
All of these are tough plants that will cope well in large planters.
The artificial turf is not something I would usually recommend, but essentially the damage is already done with the concrete base you have - there is no biodiversity there.
It would: soften the whole area and make it feel like a garden rather than a yard; reduce the glare and provide a nicer surface underfoot (there are underlay surfaces for it). But there are other options such as gravel and bark - but these would require more maintenance over time.
