foil is rubbish.
it is a piece of plastic film, about as thick as paper, glued to chipboard MDF
it peels, sometimes before the door leaves the warehouse, but especially if it is near a kettle, toaster or above a dishwasher
The other options you mention are all paint. If you can find a laminated finish (only on flat doors) it will be harder wearing.
My own preference is for timber doors, but of course these are more expensive. If you are having a pro fitter (such as a local joiner by recommendation) he can buy from Howdens (trade only supplier but they will let the client look round the showroom) which are quite good.
Kitchen fitting companies are like plastic window installers, they make a high profit and not all are very good.
Kitchen fitters are notorious for poor quality plumbing and electrical work. If you can get local recommendations, ask a plumber and an electrician to do their bit after the old kitchen comes out, and before the new one goes in.
Always ask for a local reference site, of someone else the company has recently done a similar job for, where they will let you visit the householder, ask their opinion, and look at the workmanship. Try to make sure it is not the installer's brother-in-law.
Any tradesman who can't, or won't, let you look at his work in another house, ask yourself why.
If you can't get any recommendations, drive around looking for tradesmen's vans doing similar work locally, note down the address of the house, and the name and number of the tradesman. Try to have a chat with the householder once the work is finished. Householders are usually proud of good work, and very ready to slag off poor workmen.
