Jaguar usually use clip on wear sensors so the pad descriptions are basically meaningless. You always have to buy one sensor cable per axle but these are available pretty cheaply these days.

Most branded pads will be fine. If you are picky, there are some that are probably a little better but you have to start comparing the originals with the replacement's DOT friction grades and make an educated guess. Jaguar don't seem to buy cheap brake gear so downgrading is a fairly probably risk if you are not a little careful. I would not buy pads that don't display the DOT code and I my minimum grade is FF on any car.

There seem to be two front disc sizes and maybe two rear ones. It would be wise to check the sizes on your car and then check the parts list again. I'm not so familiar with the X260. The rear list looks hard to follow

I took a second look. Did you get the same part numbers?

Front 350 mm discs:
T2H16147 or T2H53848 or T4N14764

Front 325mm discs:
T4N13434 or T2H53847

Rear:
Both sizes use the same pads
T2H52754 or T2H53866 or T2H9989 or T2H53849

Generic sensors should be fine. They are made by/for brake manufacturers and J aguar don't make their own either

A very rudimentary check suggests that the rear discs are 20 mm thick when new and can be worn down the usual 2 mm to 18 mm.

The 350 mm front discs are 32 mm thick.
The 325 front discs are 30 mm thick.

Again both have the usual 2 mm wear limit at which point the heat capacity of the remaining material drops below the set limit.

One slightly deeper groove, probably caused by a piece of grit wedged in the pad is of no concern.

Aren't these the originals: JAGUAR XE RANGE 2015 ONWARD REAR BRAKE PAD KIT FROM ATE. PART T2H53849-A | eBay

Modern ventilated disc are mechanically very stable and could very probably be worn down below 2mm and still operate adequately under typical conditions. But they are sized to still be thermally stable at the min. dimensions - stand up to heavy use even though a lot of material has been removed. Under these conditions, they could overheat and then brake performance would take a dive. Manufacturers are going to specify slightly on the safe side but crash/insurance investigators also work from the same starting points.

I thought the XE and X260 factory brakes were TRW? 325mm rear rather than 326 ATE.

I 'm not sure about this. It appears that many Jaguar boxed pads at least have the TRW logo painted on the thin backing plate but the pad underneath has the ATE/Galfer markings. I wonder if the hadrware was originally ATE but TRW also supply some discs and pads and rebadges ATE stuff where they don't have an alternative. I wonder if it is more supplies than engineering here. I don't know the XE and XF X260 parts so well but whenever I try and find what the originals are, there tell a mixed story
