I have a buffer chest in my main factory, and I try to keep perimeter repair turrets stocked with repair packs so it's less power to heal entities (because it doesn't have to jump). However, my buffer chest steals all the repair packs from the turrets. This doesn't feel right... the repair turrets shouldn't act like a passive provider or storage chest.

I don't know, this doesn't seem like something I can fix, its just the base game logic

Could you make the slot in the repair turret a buffer chest with repair pack request of count=0? This way it won't auto-fill, and it won't be stolen from unless requester chests have "take from buffer chests" selected?

Hmm, seems like roboports have the same fault. Nevermind then. I'll workaround it.
