There's the classic risk/reward on the approach shot for 4.
For me, the risks far outweigh the rewards. The front bunker is a terrible place to be on that hole, especially towards the middle and away from the green.
I avoid it at all costs. My ideal approach shot is around 20-30 feet on the green to the left of the pin. It's a much easier putt than it would seem, and you'll birdie from there much more often than popping one in from that sand trap.
This works out well for both mishit scenarios as well.
If I miss right on the swing meter, I'll typically end up with a shorter putt or right on the fringe next to the sand. Misses way right will end up in the sand, but that's more rare.
If I miss to the left, I'll end up with a relatively easy 13-16 yard pitch shot. I have a much better chance of pitching that shot within 1 yard of the hole than out of the dreaded bunker.
That's my strategy for 4, but I do play with the tour starter irons and most of my strategy revolves around those clubs and their limitations.
Both 4 and 5 I aim for par, but want to avoid bogey (or worse) at all costs, especially since I can get to hole 4 at -3 since the first 3 holes are birdie holes.
