Do I Need API SP?

Nope
Another "nope" here.
The main benefit, as far as I can tell, to using SP oil in an older vehicle is if it has a timing chain.

Do SP oils have more/better anti wear additives over SN+?

In what way is an SP oil more beneficial to a timing chain than an SN or SN+ oil?

Can someone please explain the specification as it applies to timing chains.
I'm not at all bothered by using the latest spec. Just curious if there's a benefit using SP over SN+ or SN in the Camry's engine. It's nice to have more information about the products I use.
There are a number of threads here on this subject plus information from the oil majors.
Here is one.

10 year old Camry?
That's THE car for clearance oil. If it's on sale, pour it in!

Here's a good thread to start with:
ILSAC GF6 Chain Wear Test
Here is a bit of info on the new GF6 chain wear test. It’s done under the banner of the ASTM. It’s called ASTM D8279. I have two screen shots and an ad from Valvoline referencing it. Enjoy .

When a whole class is drawkcab paddle-bill, the previous class will basically just go away, but the marketing folks will still put the letters and logos on the jugs.
Better question to ask is, what oil is not SP ?
Not even sure why all this investment into new oils and such when the whole transportation industry is moving towards EV's and H vehicles.

ICE vehicles are still a huge majority of the vehicles on the road by far, and will be for many years to come.
Using SP rated oil has some benifits as discussed in the linked articles showing the spider charts. It's not any more expensive, so just use it instead of trying to find old API oil on the shelves, if you even can by now anyway.
When someone contemplate using API SP oil for an older/old engine and many would vehemently advice not to, I laugh and imagine someone asking "I heard about a new medication for high blood pressure, should I ask my doctor to prescribe it to me? nay sayers will answer: NOPE you don't need it. It was used when you were born, use whatever was there when you were born, you're good enough with the 60s medications" lol
