Bore scoring is not an issue whatsoever in 2.7-liter engines, just as it is not in 2.9s. IMS would be the only minor worry. IMS failures are relatively low, but also these cars aren't getting any younger.
I chose a 2.9 for no IMS, slightly more power, significantly improved oiling system (the M97 system is a flawed design), closed-deck block, larger S-spec brakes, 6-speed gearbox and availability of LSD.
You will be more than happy with a good 2.9, they are widely considered to be the most reliable contemporary flat-six Porsche engine. I hope the PPI goes well. Be sure to come back with any concerns when you get the results.

Foggy headlights might indicate the car wasn't always garaged, they tend to do that when they are exposed to the elements for long periods of time. Not uncommon for a car that was once a daily driver and probably no need for real concern. Wiper blades are an inexpensive DIY job, obviously. Power window issues seem to become more common as these cars age, but parts are easy to find and not all that expensive.
The front end vibration and steering shimmy are likely related. Could be as simple as an unbalanced wheel, the car needing an alignment, or even an object in the tire. I once had a steering shimmy over 60 mph after I picked up a nail in a rear tire, oddly enough. It would be nice to identify the problem before agreeing to buy the car.
Injectors/plugs are routine maintenance items and a moderate DIY job. I suppose coil packs could be related as well. Figure well under a grand for parts if you can DIY the replacements. Add maybe $600-$800 for labor, if not. You'll be good to go for many years and miles after replacing these.
I can't tell you much about the codes, but sometimes a low battery is the cause. If the battery is old or the previous owner let it discharge recently, that could be all it is. Investigate further with your mechanic and see if it's worth clearing them, then driving the car to see if they come back.
None of these issues would be deal killers for me, assuming none of the codes are serious. All the rest just sounds like some minor deferred maintenance on an 80k mile Porsche. Certainly nothing out of the ordinary.
Good luck!

-The front tires vibrate while driving.
- Steering wheel shimmy on free way.
If it's a warped front brake disc, these two are covered. If so, then at some point the brake caliper has siezed holding the pad on - not a big deal.
I would drill down into those code more than anything, specifically I don't like the sound of "Many modules have cluster communication codes."
Nothing else is a big deal or would be a deal breaker for me, just typical stuff for any car at that age/milage.

An uneven idle could be a ton of stuff. My 2011 Cayman base had a slightly rough idle and notable vibration between 1800-2200rpms when revving in neutral. The primary problem was a torn engine mount and a failing dual mass flywheel; both components were original to the car and had 69K miles at the time. My car was CPO'd too and the Porsche dealership missed all of that. You can't tell if the engine mount is torn without removing it.
I'll also note that the 2.9 idle is rarely perfect. My 2.9 occasionally has some very minor vibrations at warm idle. The rpms don't bounce, but it is not velvety smooth like my 2016 BMW M235.
Chances are the engine, trans, and clutch/flywheel are the original parts and will require replacement soon. I've done the clutch, flywheel, engine and trans mounts, two vacuum lines (both had cracks, likely causing a minor vacuum leak), coil packs, shifter cables, belt tensioner, AOS, and tons of other small stuff. I've put in over $7K in maintenance/repairs on my Cayman to get it back up to snuff. I would have spent a LOT more if I didn't do all the work myself other than the clutch/flywheel. Luckily the Porsche dealer reimbursed me $3K for the clutch/flywheel so I'm only out about $4kish.
Expect to put $3K+ into the car within the first year. These are older cars now and the only "maintenance" most people have done is oil/filter, plugs, brakes, and maybe a belt.
Here's my experience and everything I've done to my 2011 Base. I still need to fix the failing headliner and replace the suspension (doing a Cayman R setup):
