I have, a few times now. The last time was just before lockdown in March last year, so I've never seen the completed project, nor got a photograph of the veneered doors, panels, pilasters that made up the wardrobe and other bedroom elements - I was contracted specifically to do the veneering, and not involved in building, finishing, or installing the work. On that occasion the job comprised roughly 75 - 80m² of panel faces veneered on both sides, most with walnut on both sides (doors), and some panels, hidden on the back face, that had a cheaper balancing veneer applied.
The engineered walnut veneer sheets I worked with were all about 3m long by 600 mm wide. Most of the panels (doors mostly) were about ±2,400 mm long by about 450 - 550 mm wide with other panels at different lengths and widths. Because they were engineered each sheet was near enough identical which means a book match wouldn't gradually change over a wide series of panels, although in my case I did a slip match, which worked equally well regarding consistency of pattern across the width. As to working with the stuff, especially on this scale, its positives are consistency of pattern, stability and lack of faults, such as lumps, bumps, voids, and so on.
Mostly it was a case of cutting to size ensuring consistency in pattern repetition, and careful preparation of edges where they had to be taped together. Lacking a guillotine, cutting to size was undertaken with an MDF straight edge, a veneer saw, a sharp Stanley knife, and straightening edges that had to be taped together with a handplane lying on its side with a cobbled up shooting board, i.e., the two pieces of veneer trapped between two sheets of MDF with the edges barely protruding. Glue-up was Titebond veneer adhesive (mostly) in a vac-bag with a melamine faced base board and a melamine faced board on top with a series of very shallow grooves cut through the melamine of top and base board to aid air passage. In some ways, getting the panels into the bag and sealing it properly was possibly the most challenging aspect of the job.
Anyway, I can say that this type of veneer product is a good option in many ways, especially for a large job. Slainte.
