If your mission profile is to essentially stay inland and sail in decent weather, the necessary capability of the boat isn't going to limit you much. Tillers, wheels, inboards, outboards don't matter, they are all acceptable. You may focus more on what you need to be comfortable aboard with two people for whatever length of time you intend. 24 ft is pretty cozy for two people, unless they intend to be cozy. Do you need a private head, and therefore, a holding tank. How about a galley, refrigeration, separate sleeping quarters?
You should also consider you budget to outfit a boat beyond its purchase. Essential life saving equipment, communication, navigation, lines, fenders, and on and on can chew through a small budget quickly, if they aren't included.
