Honestly everything on your list but the tarpon is designed to stand in and will paddle better than the diablo in my opinion. Go to a demo day and paddle as many as you can before you make your decision you might find another boat that fits you better. My only other advice, don't underestimate your need to paddle farther, once you have some familiarity with the water and have to go a bit farther for fish as the seasons change you will realize the need for a boat that will cover water.
