If the walls are open and you can get up to the attic (or basement) to run the wiring, not too bad.

I am not a fan of wireless (partly due to expense and lack of perfect reliability) but these are an option.

You can easily do as many switches as you want. If the electrician doesn't know how or wants to charge a lot, you need a new electrician. https://www.easy-do-it-yourself-home-improvements.com/4-way-switch.html

@zneret I believe the walls will be opened, maybe a couple. So what I'm sensing is that it shouldn't have to cost an arm and a leg or be too difficult for a good electrician. That's great to know. Right now there is only one light switch and it's behind the fridge. Other things in this home needed to be addressed before the kitchen but we're getting there!

Yep. I've always detested the 3-way/4-way nomenclature, but you can (with four way switches) put as many as you like in there. My outside lights on my house must show up on about four or five switches.

Sort of related; I have my outside lights on a smart switch so that I don't have to remember to turn them off or on. They automatically are wired for sunset and sunrise. Very convenient!

You could install a motion-sensor switch (aka "occupancy switch") that would turn the kitchen lights on whenever somebody entered the room, eliminating the need for a switch at each entrance. You'd just have to make sure that the switch did not face a hallway or another room so that the sensor would not triggered by somebody just walking by. This Lutron MS-OPS5MH-WH can be trained to not turn on the lights when there is sufficient daylight. It can also co-exist with other switches.

@wdccruise Would I need only one switch? How does the 3-way switch work?

A three-way or four-way, for that matter, can be used as if it were a regular (so-called 2-way) switch. It's just got more contacts,
