Like you, I use Apple devices, and they work together very conveniently. Apple TV has great features when used with other Apple devices. What brand is your TV, though? Most well-known brands have the Apple TV app, but it's better to check here:
https://tv.apple.com/. Even if your TV is from an unknown brand and doesn't have the Apple TV app, I highly recommend using Apple TV, especially since you have other devices from this brand that work well with it. You can try the free trial and decide during that time.
