Plants climb in four different ways, and each one needs a different frame. Choose by climbing mechanism, not by looks, and skip the pockets entirely.
A tiny patio is a floor-load space with borrowed boundaries. Settle what the floor sits on, who owns the walls, and what space you can lose first.
Fence panels are infill, not structure. Send the load to the posts, keep the planting open so it does not act as a sail, and check whose fence it is.
