Can anyone give me some advice/recommendations on hedging.

Having read your requirements and your rural location my immediate thought
was Hawthorn.

British native so excellent for wildlife and the environment.
Used by farmers to keep livestock in/out.
Flowers.
Berries.
Can be easily trimmed. But remember a hedge should be "A" shaped in
cross-section not with vertical sides (and never "Y" shaped).
Grows thick and very thorny.
Can get "whips" cheaply if buying lots.
