Here's the challenge with going from a sim flyer to real-world flying (and I say this as someone who is working on his Commercial/CFI, and spent an inordinate amount of time on Flight Sim as a teenager):
Most people who transition from the sims to real-world don't develop the proper scanning techniques outside the cockpit. Because we're so accustomed to flying on instruments in the game, it can be extremely difficult to get student pilots' heads outside the cockpit and using attitude flying and good traffic scans.
Here's my advice: if you're serious about getting a PPL, skip the sim. It can be done, but I don't recommend trying. I was one of the "lucky" ones who had no issues transferring from the sim to the outside world, simply because above all else, I love the view, but for every one of me there's 10 who struggle (not trying to brag at all, just telling it like it is).
The sim can be a terrific way to chair fly instrument procedures and scanning techniques if you move on to your instrument, but even then, use it for workflows and instrument cross-check rather than as a true substitute. Tuning NAV radios, identifying VORs, practicing DME arcs, etc. can all be done to a certain extent with a sim. Even flying instrument approaches with real world charts can work, if you change your view such that you can't see outside.
You'll notice that almost none of those are things you work on as a private student, and that's with good reason. If you can't navigate by pilotage and dead reckoning, relying only on the GPS you're screwed if you lose your electrical system.
I'd say the only real benefit to a private student is instrument familiarization, but beyond that, you're likely to do more harm than good.
And trust me, I say that as someone who completely understands just wanting to immerse yourself in flying. It's all I wanted to do when I was a private student.
Listen to LiveATC (download the app and listen to it when you're driving instead of music). The biggest thing student pilots struggle with is ATC communcations.
Good luck! Feel free to ping me if you have more questions as you go through your training. I should have my CFI in about a month.
