You don't need a boat of that type for safe cruising in our waters - only a minority do so. The three you mention are actually very different types of boat although there is a connection between the CO and Sadler for obvious reasons.
There is a much wider range of boats available than long keel or even fin and skeg that make very good safe cruisers, and depending on your budget, looking at newer boats may get you better value.
By your own admission you know little about boats, so you might like to ask yourself why so few people own long keel boats.
+1. In my (limited) experience many French harbours have limited space and room to manoeuvre - a long keel would not be on my preference list due to difficultly under engine in small spaces
