I recently finished a Lutron Caseta light switch setup. When people ask about smart light switches, I always steer them toward Caseta. Why? As opposed to Philips Hue or other bulb solutions, Caseta has the smarts in the switch, not the bulb. This makes more sense for many reasons. First, if the tech smarts fail for some reason, the light switch is still a real light switch. Second, you can choose any bulb you’d like, with particular warmth and quality you choose. And third, in my experience Caseta is more dependable and bulletproof than other solutions.
Smart lights aren’t a necessity and many folks won’t find any utility in them. I enjoy being able to hook them up to smart speakers such as HomePod. This makes it easier to turn on and off lights if you’re running around and have your hands full. It’s also easier to set up automations for when you’re out of town. They even can be set up with sensors to automatically turn on. All of these are minor improvements though, so this is still a nice-to-have, not a critical part of your technology.
There are other switch based solutions, but Lutron is a big name that has been doing this for a while. I wholeheartedly recommend them. (Not an ad)
