"Blackberries, for example, are widely eaten as a wild food in Britain, while the name Ivy holds a special place for some." Ok, gotta stop you right there, lol. Blackberries, particularly Himalayan Blackberries, in the PNW are a prime example of what makes something a noxious weed. They will decimate an ecosystem. There are a lot of 'weeds' that are called such because they're 'not the plants you want' in a certain spot. But then there are weeds that actually threaten habitats. English Ivy is another example. What's native somewhere (this article appears to be centered in the UK) can be a terrible idea elsewhere. Blackberries are delicious – but if you let them reproduce, they will absolutely take over and smother out all of the delicate balance that so many species rely on. My recommendation is to keep it simple. If you have a monoculture lawn and you want to add some diversity, start with something like clover. You will see a TON of pollinators. Then pick edges where you can maintain wildflowers. In our area it would be things like Lupine and Douglas Meadowfoam. Different kinds of irises, etc. You can likely find a native seed mix for sale near you. A lot of people have mentioned things like Yarrow or Queen Anne's Lace. Keep in mind that many of these plants closely resemble Poison Hemlock. This is another reason I like to keep things simple – I like to have a good sense of what's growing, so that a child or an animal doesn't accidentally pick and handle something toxic. Source: I've restored and now maintain over 20 acres of Oak Woodland and Upland Prairie in collaboration with our local NRCS branch (our local Soil & Water district that's part of the USDA). I even seeded nearly 6 acres of it – an incredibly steep slope – entirely by hand.
