I know both boats assuming that you are referring to the 240 Hunter as I use to be a dealer for both. First, both boats are well made so we will not go into construction although others have their own opinions.
The room in the cockpit should be given consideration for your age. There is no question that the cockpit of the 240 has more room. The 240 has a walk thru transom with a fold down ladder whereas on the Catalina 22, you have a stern rail to climb over to access the boarding ladder. The halyards on both boats are led back to the cockpit as with all sail control as well. Both boats have a porta poti placement inside the cabin but the 240 cabin is roomier.
The 240 Hunter is water ballast and on the Catalina 22, it is either a fixed or wing keel depending on the style keel. If the Catalina 22 is a swing keel, it is easier to load onto a trailer than the keel version.
As for docking, I would suggest for you a long finger pier for your age. It does not make a difference to me as to which boat on this point.
Now this will be stepping on many toes. For small boats to include the two mentioned, generally you will sail faster flatter and that is true for the Hunter 240 and Catalina 22. Anything over 14 degree heeling is unnecessary as I use to race both competitively and for your age this should be seriously considered along with anyone in the cockpit. I sailed against the best and a lot depends on the winds, sail control and amount of sail that is necessary.
Good luck in your decision.
