I think will be very comfortable to connect the patio with a sliding door.. With this door will have and integrate space, outdoor - indoor... And will add more light to the interior space..

IMO you already have too little cabinet space and now you want to eliminate more to get french doors I would say no to that and maybe just a nice door all glass .

Rip out the dividing wall between the kitchen and the room wiht the pass thru. Love the slider door idea. Easy access and lots of light.

Sliders are not to visually attractive - see if there's a different door to replace. I'm liking the french door idea. If you're looking to add more light, how about a french door and a window?

Go for it.

If you have enough cabinet space go for it.

Nice idea Amanda and a slider or french doors would bring lots of light into the kitchen. Here is another option that could work well and is in keeping with the style of your Cape Cod home.

Yes, good idea, and while you are there, you might want to consider making one large window, rather than having the two. You'd then create more upper cabinets.
