I would recommend talking to a Kitchen Designer. They will be able to evaluate your wants and needs and see the space/surrounding spaces for themselves. They will then decide what the best layout may be for you. From what I'm seeing and the little information I know about you and your home, your options look good. I would consider traffic flow. The red lines indicate traffic from the lower level to the living room. 1. Something to think about: The peninsula directs traffic right through the work triangle. This traffic may interfere with the person(s) who are using the kitchen and could be annoying after awhile. However, if you don't plan on going outside often, or you have another bathroom on the main level, you may not have a lot of traffic from the lower level to the main lvl. 2. The island layout is nice because it directs traffic through only one section of the work triangle. The island will keep people out of the range and fridge zones if they're simply walking by. The downside is that you would be cutting through your work triangle....You can always add a prep sink in the island to help with the cut interference.

Decided as yet? Wil the island have seating? And is this open plan? They can, or they can not, but some more information is needed to have an opinion on whether they should. Could you share, for instance, the space limitations? Just do avoid an 'almost' lines up situation. It should be deiberate either way.

Regarding the refrigerator...you're right to be concerned. It's not located very well. First, it should be on the perimeter so you aren't drawing people who are not working in the Kitchen into the main working part of the Kitchen if they are trying to get to the refrigerator for a snack or for condiments/drinks when setting the table. (Or even just for ice for a cold drink.) The current location is made worse by the peninsula that blocks access on the left. Anyone going to the refrigerator must go around to the right. Second, the doors of the refrigerator must extend out past all items adjacent to it -- walls, counters, cabinets, etc. As it stands in your proposed layout, you will not be able to open the refrigerator doors fully for full access or for cleaning. You need around 12" b/w the wall and the refrigerator. Third, are in the USA now? If so, know that refrigerators are standardizing on 36" widths, so don't constrain yourself with a narrower space b/c it could be difficult in the future to find one narrower than 36". So, plan on at least a 36"W x 72"H space for the refrigerator. My suggestion is to move the refrigerator to the range wall on the end. You can also now have dish storage above & next to the DW. You could also move the peninsula to the other side and have the refrigerator & pantry cabinet(s) on the other side. Something like one of these (note that these are based on very rough estimates of your dimensions. Actual dimensions may change cabinet sizes and workspace sizes): All work zones are nicely separated. There can be multiple people working in this Kitchen at the same time...prepping/cooking, cleaning up, unloading the DW, etc. There's room for at least 3 people. If no one is cleaning up or unloading the DW, then the Cleanup Zone can be used as a third Prep Zone. The refrigerator is on the perimeter where it's easily accessed from the Prep & Cooking Zones as well as for someone looking for a snack or setting the table with condiments or drinks. Someone getting a snack or getting dishes for setting the table will not have to cross through the Prep and Cooking Zones. Note how the Cooking Zone is protected from through-traffic, this is very desirable as this is the work zone that should be the most protected. The best MW location is in Layout #2, also on the perimeter like the refrigerator. There's a Snack Center. However, it's at the expense of the two tall pullout pantry cabinets. In both layouts, the counters on the sink run are 3" deeper than standard to add additional counterspace. If it's within the budget, get 27"D base cabinets/drawer bases as those 3 extra inches of depth add a surprising amount of additional storage space. If deeper cabinets are not in the budget, then simply pull the cabinets out from the wall 3". Note that narrower pullout pantries are more efficient and more accessible storage than wider pantry cabinets. With pantry cabinets wider than 18", things can easily get lost in the depths of the cabinets. However, with pullout pantries no wider than 18", everything is visible and easily accessible.

If you haven't yet set where the electrical connections are for the range, I'd center the range between the pantry cabinet and the wall so the wall cabinets on either side are the same size. Don't do corner cabinets. It's a dated look.
