Welcome to the forum. I agree with Unthrottled: petrol would probably be best for your needs, not least because a well-used diesel can need expensive repairs.
To an extent at your budget level, condition is more important than make or model; secondhand French cars are more of a gamble then others because although they can be very good if properly looked after and well-driven, they are more likely to go wrong if neglected or abused.
Something straightforward like a Focus or Astra should suit you, as there should be plenty around to choose from. If you want more room, there's the Octavia or Mondeo and various medium-sized Japanese estates (although there won't be as many of those around).
