Dishwasher and extractor hood in IKEA METOD kitchen

I am buying a new Ikea kitchen (METOD with Bodbyn fronts). I don’t like the built-in appliances at Ikea, so all appliances should be purchased from other manufacturers. The oven and hob should not be a problem. The difficulties are more with the extractor hood (which should be built into an 80cm wide cabinet) and the dishwasher.

Since I am buying everything new: What do I need to pay attention to in order to install both? (Especially the attachment of the front to the dishwasher is problematic?) Have you had good experiences with certain appliances that you can recommend?

Dishwasher Bosch / Siemens / Neff XXL with Vario hinge. Extractor hood is difficult because 90 cm is standard. A good option would be Berbel Firstline Touch BEH 80 FLT

Hello,
Keyword extractor hood:
Look for "Lüfterbausteine". These are universally usable/installable and are offered in various widths.
An example would be the parts from Siemens. In this case, the bottom of the wall cabinet is cut out to the dimensions of the Lüfterbaustein, and the part is installed in the wall cabinet on the countertop similar to a hob.

The extractor should extend across the entire width of the cooktop. This becomes difficult with the fan module, which according to the dimensional drawings requires a cutout depth of 35 cm. The remaining space would be too narrow to securely support the device.
