After all this time watching what the community does, what you do, in these programs I wouldn't say you're limiting yourself. Of course you can do extra stuff in post but to be honest the number of things you can make with the hundreds of variations at our disposal is so colosal the only fair word to describe it is "infinite'. So nah, I doubt you need postwork.
Now if only one of the softwares decided to add a basic function to add text / watermarks / frames, that would be great. Ok, text function is a lot to ask, maybe just an a white or black frame and the watermark.
