It sounds lovely. The ceiling will be more than suitable for a transitional style. I think the wainscoting would also be fine but as I'm cautious I'd be adding after I'd lived there for a while. It does seem more traditional than transitional. On the other side I'd love the bead boarding in the hall.

Having been brought up in a Lockwood home I can appreciate your love of the wood. I notice you have a light green bench and that would blend nicely with some similar colours in the room. I would consider having your cupboard doors replaced or sprayed to compliment the bench or visa versa you can have your bench updated with a new finish to modernise it. Perhaps you could just price out the cost of a new bench and leave the rest of the kitchen as it is. The odd bit around the dishwasher looks weird and that might be able to be fixed by curving a new bench into a small breakfast bar type set up. If there is room I would also reposition the microwave to the right of the cook top and use the existing space for a display or a lovely pot plant.

Not keen on tiles ... prefer a smooth surface with no grout lines to try and keep clean

What an amazing transformation! I LOVE those cabinets!
