The side stand puck is easy enough to stash under the seat or in a pocket, but I really like my Cortech micro tank bag. It has a phone pocket and a small pouch that you can put keys, insurance card, and a couple granola bars. I keep my side stand puck in there

If you are dead set any sort of bags attached to the bike, a hydration backpack will solve your water carrying needs, allow you to drink on the fly, and have space to carry some stuff. There are very minimal designs all the way up to big backpacks. Here's my single sided bag. I like that you don't see it when viewing the right side of the bike. It also has a cutout to fit around the turn signal. Let me know if you want more info and I can dig up the link to the bag and saddlebag guard.
