Edit:

This plant/location in the garden is especially hard to photograph. It's hard to reach, dark, and surrounded by thorny brambles. And there are lots of different species of plants in the same spot; it's hard to tell what leaves are attached to what plants when viewing a photograph.

Rather than take another dark, poor-quality photo during the day, I made a video at night with a bright light. I tried to show that there are lots of differently-shaped leaves attached to the same plant. Some leaves are simple leaves. Others are compound leaves of three.

Answer 1

As a novice, my guess is Boston Ivy (Parthenocissus tricuspidata).

Eastern Poison Ivy vs Boston Ivy

Boston Ivy: A deciduous woody vine native to east Asia, introduced in North America. Established in numerous scattered locations, mostly around urban areas. It is a close relative of the native Virginia creeper.

Middle leaflet has no stem or a short stem not much longer than that of side leaflets.

Plants can have both compound (trifoliate) and simple leaves. Some leaves have two side leaflets fused to create a two-leaflet leaf.
