The Miyawaki Beach Popper (for example) tends to ride low in the water, the idea is not to cause a huge commotion but simply to to create a v-wake on the retrieve that suggests a wounded baitfish. In fact, the MBP is technically not actually a popper, but a slider, that is, the popper component is positioned with the pointed end forward. The usual technique is to make a quartering cast down-current then retrieve, varying the speed until you find something that appeals to the fish.

Sea-run cutthroat are often found feeding much closer to the beach than coho and it is an excellent idea to wade no more than knee-deep while casting at a very shallow angle to (or even parallel to) the beach. While coho can sometimes be found chasing bait into the shallows they usually tend to stay a bit further out.
