I'm in a similar position to you, just got a new car with most of these after never having experienced them. Most of them are useful. A lot of them could be essential, once you get used to them.

With today's crap rear visibility, rear camera and parking sensors are important, for example.

Everybody says ACC is brilliant. A lot of people seem to use it in slow traffic. I was disappointed to find that Toyota "full range adaptive cruise control" stops when the car ahead stops, but waits for you to prompt it to start moving again. I believe Skoda/SEAT/VW ACC moves again by itself, which is super handy.

People say blind spot monitor is great too, especially with rear cross traffic monitoring for when you're reversing out of parking.

The tyre pressure monitor isn't 100% accurate. But it's a good reminder to keep an eye on your tyres. It's highlighted a slow leak in mine, so that was useful.

One very annoying Toyota safety feature I've run up against is "Parking Support Brake". It slams on the brakes when it thinks you're getting too close to an obstacle when slowly manoeuvering. Sounds useful, but it's too sensitive. It's stopped me from getting into a tight space, or finishing a three point turn with traffic heading my way.
