Probably any lens and any modern camera can achieve this quality and look. The soft background is achieved by using a lower f-stop. In this example the background isn't really too blurry though so you shouldn't need anything special.

You'll need to spend more time on lighting than anything else to reproduce the overall feel.

It’s also about proper lighting and good color grading. But a basic setup can do this. And use Final Cut Pro or Davinci Resolve for existing/grading. Premier too, but less recommendable to start.

If you’re thinking of producing content that looks and sounds this good, proper lighting and sound reflection deadening is key. When I have hired cinematographers to produce content like this, they show up with a whole lot of lights, reflectors, etc. along with high quality microphones.

Really anything with a fast (low) aperture will give you the ability to do it in most environments. Something under 3 is usually a safe bet.
