I forgot to add I need to replace the tile floor, too.

What you are proposing would be costly, and you won’t see any return upon sale.

The cabinets look to be in great shape, and fortunately, they aren’t arched...that’s what truly dates a kitchen. Peruse the threads on oak kitchens here, and you’ll see many that are much more “orange-y” than your folk’s.

As for changing the counters, adding a backsplash, and replacing the floor...most likely, anyone purchasing the home is going to want renovate the kitchen to fit their own taste. They might choose to extend cabinetry along the range wall. The appliances look newish; the kitchen is quite livable, while the new owners contemplate changes.

For sure, remove all clutter from atop the fridge, and on the doors.

What is the condition of the rest of the house?

I agree with darbuka - I wouldn't spend money on the kitchen at all. As a potential buyer, I would be thinking about remodeling the kitchen - and if that meant ripping out brand new counters, I might just say no to the house.

I would take down the pot rack on the wall, and the shelving unit - they make the statement that there is not enough storage space in the kitchen. That might be the case, but you don't need to draw attention to the fact! And if storage is really lacking, that's another reason a potential buyer might want to remodel.

You won't recover your costs. Please clean everything well and sell as is. HGTV and related renovation shows have promoted a myth of fixing up at incredibly budget prices to sell for profit, but rarely are the true costs divulged, especially for a homeowner who is not also their own realtor. My brother has a business of flipping homes, and in this economy, you take a big risk investing much in a kitchen renovation. You would have needed to have bought the house way below market value, used builder-grade finishes installed completely with DIY labor, and even then you may not make a profit without much experience and a learning curve from prior flips. If you do extremely well, you might recover 90% of your kitchen renovation costs as a homeowner at sale. Chances are it will be closer to 60%.

Also, oak just tends to be orange. You may be surprised at how little stain is actually on those cabinets. The oak will amber in time. The whole kitchen including backsplash, floor, counters, and cabinets look relatively good and prepared for a sale. The new owner will want to put their own touch on it and may rip out any improvements you would make.

Clean and declutter.

Use a epoxy grout colorant on the floors to closer match the grout to the tile.

Replace the laminate counters with new laminate counters. Something off white that coordinates with the floors. Formica Ouro Romano is nice and light, with the right colors. https://www.formica.com/en-us/-/media/formica/global/products/swatch-images/09277/09277-swatch.jpg?rev=6c1b2c503342416b90c1046e64c80307&fd=true&filename=9277%20Ouro%20Romano%20swatch.jpg

Fresh wall paint.

Stick on battery operated LED under cabinet lighting.

That’s it.
