Welcome to the forums! Sounds like you are in the right direction. Is there any reason you want to get the 65 tall? What are its dimensions? The reason why I ask, is that taller aquariums are kind of harder to light since the light has to penetrate deeper. Not to say a tall tank is impossible, but just a little trickier. It also depends on the plants that you want to keep. Good beginner plants that I always recommend to customers (I work at a LFS) are Cryptocorynes, Anubias, Ferns (Java, bolbitis) and vals. This plants are generally considered to be the easier species.
Also, for a tank that size, I agree and would definitely use a canister. I would recommend doing a quick google search of "65 gallon tall planted tank" to see what other people have done with that tank, and use that as inspiration. Also, if you like one of them, you can post it here and we can tell you what you would likely need for that looks (CO2, highlight/lowlight, etc.)
