We used roses at a previous house to demark our garden/lawn edge. They could be planted between now & March if bought bare rooted. Flowers & thorns, pretty to look at & good at stopping footballs!
Berberis also came to mind- another neighbour on the same estate used that & kept it cut back to a lowish hedge height. Some are very thorny, some are evergreen, so lots of choice.
Boring mahonia aquifolium is as tough as old boots- used in carparks- but is evergreen, has flowers & fruit for the birds & can be kept hedge-like too.
Native hawthorn also a possibility- thorns, flowers, fruit & prunable. J.
