Hello! I've had same choice option for my small bag. Especially, taking into consideration that the pochette NM + long strap + card holder (or round coin purse) would still cost less than the pallas clutch. The decision wasn't easy, but i realized, that i love having the front pocket + the chain is nice, and i can detach the long strap. I normally put there my id/access card. I even managed to have it the work day bag (when i plan night out after) + sometimes I attach the wider strap (from my tournelle) for it to look better with winter clothes.
I will try to make a photo of what i fit in. But normaly, its: Iphone 7, Iphone 5s, lv card holder, key cles, lipstick, passport, access card. For travel purposes i fit in a tiny umbrella, iphone 7, lipstick and metro card.
Hope this helps (still will take pictures at home).
