You can actually still get Matic J on certain websites, but its a waste. There was a service bulletin from Infiniti stating they replaced Matic J fluid with Matic S. That is the required transmission fluid now. They are still the same transmission fluid, just that Matic S is the synthetic version of Matic J.

I been using this for two years without issues:

It's just as good as Nissan fluid and a lot cheaper, I just bought 12 qts. for about 5.70 each.

I did this for my first round of drain and fill. Then I found their synthetic stuff and i'm using that now.
Castrol TRANSMAX™ FULL SYNTHETIC MULTI-VEHICLE
and here's the datasheet showing that it is spec'ed for JASO 1A

Transmissions generate lots of heat. Heat will break down the oil's ability to lubricate properly and then your clutch packs will wear down and lose material. When your clutch packs lose material they start slipping and don't become effective at transferring the work from the engine to the wheels.
The danger comes when you don't change fluid regularly. The clutch material will actually become suspended in the fluid and that will keep the transmission from slipping. So, because the suspended clutch material is whats keeping the transmission working properly when you replace the fluid with new clean fluid, the transmission is now slipping and shitty. This is what causes the myth of transmission fluid changes break your transmission.
Flushes take this a step further and replace ALL the fluid but it also usually puts some pressure in the system, or detergents or reverses the flow, so this will dislodge the material and it will now go into other areas of your transmission and make things worse. Generally a flush with a machine using detergents isn't advised. I'm pretty sure a Nissan transmission flush doesn't have any detergents though, just fluid.
so after all that...regularly changing your fluid is recommended, just like motor oil changes. However if the fluid has never been changed and it's a high mileage car, the transmission may be barely holding itself together.

If you want it all taken care of at all at the same time then yea sure.
I don't like giving dealerships my money though so I do it myself. It really depends on if you want to do a full change or a gradual one. a full change basically entails you disconnecting the transmission cooler return line and filling and pumping out the fluid until the fluid is nice and new. This takes about 11 or 12 quarts of fluid and wasn't something I wanted to do all at once.
I instead opted for the drain and fill method. Basically whenever I do an oil change I also drain the transmission pan and fill it up with how much i removed. (usually about 4 quarts). each drain and fill will remove approximately 1/3(hence the 4 quarts of 11) so you have to do this multiple times. I'm on my second round of drain and fill and my fluid was really bad the first round and its a bit better this time around. In the long run I'll end up using more fluid because I will never had completely clean fluid cause it keeps mixing old and new fluid but eventually it will be "good enough" for me.
I do them with my oil changes, so by the time I change the fluid, the new stuff i added in is about 10,000km old so it doesn't look compltely new. I'm estimating I need to do at least 2 more drain/fills until I'm happy with it in the long term lol.
You could do it all in the same day by doing a drain and fill, drive around and come back, do another drain and fill and repeat until you're satisfied with the stuff coming out being clean enough. But I've got a small child and have very little time so my oil changes/transmission changes and work on the car are usually done at like 11pm after the wife and my son have gone to bed on the weekend.
if you're doing it yourself remember to get crush washers. This is really one of the only things I buy from the dealership. It uses the same one as the oil pan, so whenever I go I usually buy 4 - 6 washers.
