I'd forget the meadow bit and sow easy to grow annuals which will self-seed year on year.
On my allotment I grow pot marigolds, sunflowers, poppies, cornflowers, cosmos, nasturtiums, poached egg plants, love-in-a-mist, phacelia and more. They're all good for bees, butterflies and hoverflies.
Either buy individual packets of the ones you want or look out for the mixed annuals seed packets which normally say what's in them.
I'd just tidy up the rough strip, weed it if you can then lightly fork if before sowing a packet or two of wildflower seeds, which are mostly perennials, so won't do much for a year or so. I'd also sow a few annual seeds, such as poppies, on there as well.
