I'm looking to anchor a tall PAX closet (100x60x236 cm) against a plasterboard wall that doesn't have wooden studs behind it. The wall construction involves cross-laminated timber with 2.5 cm of insulation and two layers of gypsum boards. The baseboards aren't coming off, which leaves the closet about 2.5 cm away from the wall. The anchors I've found for the gypsum board only hold up to 10 kg each, and I'm hesitant to rely on just that. Would adding L brackets or a ledger board help me increase the number of anchor points? I'm also considering going directly into the CLT if that's a viable option. What load capacity should I be aiming for, and are there better methods I haven't considered?

Try using 1/4" toggle bolts! They provide a strong hold even in plasterboard. I know they can be slightly hard to find in some areas, especially where concrete is the norm, but ordering them online should do the trick.
You probably don't need to overthink this too much. A decent drywall anchor should do the trick since most of the closet's weight is on the floor. Just anchor it to the wall for safety against tipping, and you'd be fine. I recommend using anchors to fill the gap left by the baseboard, about 2.5 cm thick, to give you some peace of mind.
