The drain plugs are the same as those used on VW Tiguan, GTI, Audi etc. The actual factory VW plug is $7.50 compared to Porsche at $10.

Rhino Ramps work just fine at a fraction of the cost of the Race Ramps. I find this method safer than trusting just a jack and getting under the car. Also, I use two jacks in order to lift the car evenly on both sides avoiding excessive stress on one side of the suspension.
You can just back the car onto a pair of Rhino Ramps. The car will be tilted forward which is just fine for draining.
I put my VW Eurovan, which weighs over 5,000# on a pair of Rhino Ramps, with no worry.
Top off the oil when you get the car back onto the ground and level. Check with the PSM.
There's no reason to worry about "excessive stress on one side of the suspension." The suspension can handle the full weight of the car on one wheel. Easily.
I definitely wouldn't get under the car at all when only supported by a jack, any jack. Even for a minute.

bkrantz, excellent writeup that definitely helps. I just did my second oil change on my 991.2 at 7000 miles and one year and would suggest a small refinement.
Rather than completely remove the fan connectors from the intake duct--they are very tight--I found it easier to simply separate the connector from the mount. The connector has a flat shoe on the bottom that slides into the mount. All you do is depress one side of the mount and connector slides off. Here's what it looks like:

The oil filter housing on this vehicle is essentially identical to that on my 2002 Eurovan VR6, save that the housing is on the bottom of the engine, rather than the top. The filter is similar but has a plastic core.
I've been changing my own oil on my Eurovan for at least 13 years. Probably 16+ oil changes now, at 135,000 miles, every 5k. I have never torqued the oil filter housing cover and think doing so is unnecessary. Fully seated, and snug is enough. The O-ring provides the seal. Never had a problem with the cover.
I also plan to use Mobil 1 0W40, "European Car", $22 from Amazon for five quarts. Certainly meets spec.
I also had a MINI cooper S, the oil filter housing was similar, but the cover was aluminum.
Both use a 36mm low profile socket to remove the cover.
The gaskets for the oil heat exchanger, and the housing itself (where it attaches to the block) will fail in time, and leak. I assume the same will happen with a Porsche with enough miles and years.
Waiting HOURS for the oil to drain? Wow, that's really crazy. I plan to wait with my new 992 until it's just a slow drip. I owned two 911's previously, and did my own work, including valve adjustments (thankfully, that's gone). I put 140,000 miles on one and 108,000 on the other and never had an oil-related issue.

But they've been using plastic oil pans on VW's and Audi for several years now. I frankly think they can probably take an impact as well as an aluminum pan. Aluminum pans crack when hit.

I recently read an article that said Porsche engineers dropped an engine onto the floor from 39 inches in the air to prove that the oil pan was durable.

But think about what is likely with a rear-engined vehicle. If you hit something on the road, it won't be a direct impact like might occur to an oil pan in a front-drive car. It will be a scrape across the bottom. It would most likely survive.
As far as plastic degrading from heat cycles? I'm not worried about it in my lifetime.

Seeing this thread pop reminded me to check if the NAPA Auto Parts Mobil 1 sale was on, since I have an upcoming oil change. It was.
I bought 12 quarts at my local NAPA store to add to my current stash of 6. Picked them for $5.79/bottle of 5W-50. I'm good for at least another couple oil changes now.

5W30 temperature range overlaps with 0W40 from -22F to 86F.
I don't see any issue whatsoever, at least at this latitude.
And the VR6 in my van is basically the same motor used in the base Cayenne and Panamera.
I don't think I've ever seen evidence in my lifetime of a motor that provably failed because the wrong type of oil was used. Motors fail because (1) the oil is not changed for very long intervals (longer than manufacturer's specs) and (2) running without enough of it.
