Try the Ikea one for something very basic. Or Sketch Up. Both are free. For paid, the homeowner version of Chief Architect, usually labeled with BH&G's label is pretty easy to learn.

For the right side, consider a shallow cabinet that opens in the direction perpendicular to the fridge. This could be, for example, 12" deep, which is great for storage. Assuming a 36" fridge, this would leave room for a 24" cabinet/counter area to the left for your coffee area. Here is a sketch of mine; my shallow cab is only 9" deep, which still works great.

The left one is the more traditional layout. But I see what you like about the one on the right. I'm in a house rather than an apartment, but my layout is very similar to your right option. The kitchen is dead center of a large room that has the DR on one end and the LR on the other. There is a garden in the center. With that layout, I can see you shifting the dining table down to the center section, and having a desk or other small sitting area up at the top, adjacent to the second bedroom. If you go that way, you might consider shifting the door on the hall bath to the top, so one isn't "in" the kitchen when going in and out of that bath. I also wonder about the set-up for the TV. I know the furniture placement isn't a done deal, but I don't think it works with the TV in the corner. You could consider mounting the TV in a recessed fashion on the wall that backs up to the master closet. Put it on an arm that will allow you to swivel it out if necessary.

Don't forget that when designing a custom home, experienced designers look at site planning, interior planning and exterior architecture simultaneously. Don't make the common error of trying to create the "perfect plan", and ignoring site design and exterior architectural design. Good luck!
