How do I prune a Goji berry bush to keep it short?

Hi Everyone!

I am soon going to plant a Goji berry ("Sweet Success" variant) bush in my 10x10m ~ 30x30 feet community garden lot. This plant can can grow up to be 2-3 meters ~ 6.5-10 feet tall. I want to keep it under 2 meters tall or even lower than that (other plants need light, I want to be able to harvest it easily and my space is limited). It's going to get full sun and it will be on the edge of my hillside lot. I have no experience with pruning, coppicing, pollarding. I couldn't find guides on line specific to Goji berry. How do I go about this?

Goji Berry Trimming Guide Key Trimming Times: Inactive Season (Late Winter/Early Spring): Heavier trimming to remove dead, damaged, or weak branches, and control overall height. Early Summer: Pinch off top 2-3 inches of new growth to (help increase/show in a good way) bushier growth and more fruiting spurs. Simple Trimming Steps: Clean Cuts: Use sharp, clean trimming shears. Remove Dead/Damaged: Take out dead, broken, or diseased branches. Thinning: Cut out inward-growing or rubbing branches. Shape and Shorten: Trim back remaining branches. Lightly trim new growth tips in early summer. Important Notes: Goji berries fruit on new growth, so regular trimming is extremely important. Trimming prevents overgrowth and (helps increase/shows in a good way) working well and getting a lot done.

My Gojis yielded disappointing berries but cuttings rooted easily in water so I planted them over a hillside for the bumblebees and birds.

I'd try bending the top to the earth and weighing it down with a rock until it roots and voila! a trimmed Goji and a gardener's gift.

Seems to me that the most important thing about pruning goji berries involved constantly pruning root suckers so that they don't take over the entire neighborhood.

I haven't read anything before about Goji berry being invasive.
I recently found this: "It wasn't until my goji berry seedlings were all at least 12" tall that I discovered they reproduce in volume via runners." This happened in zone 8a.
I don't want to use plastic. Other than planting it in a big pot, how can I prevent it from spreading?

This might be certain species...around here it's spread by birds and we mostly find it at the margins of pine forestry and shelterbelts. I've not seen any tendency to suckering on the ones in my immediate vicinity but will start paying close attention.

Finding this true about Juneberries as well, although bush height also is preventing good coverage with bird netting.  Seems like each new seasonal wave of waxwings and robins starts harvesting earlier, even before full berry ripening.  Do you use a tiller to knock back the suckers?...  I've just been using a push mower, which I know doesn't really solve the deep-rooted problem (all pun intended).

What USDA hardiness zone does  "Cfb - oceanic temperate" correspond to?

No idea. Maybe 9 or 10. It's not very relevant to this part of the world. Our temperature range is typically 5-15 C in the winter, 15-25 C in the summer. We get a handful of nights below freezing, but -2 or -3 is as cold as it gets. And the hottest day of the year might struggle to hit 30. So we can grow lots of subtropicals and even things like bananas if they don't require summer heat.
