I bought my first Xbox S All Digital on Black Friday. Picked it up for £80, an absolute steal!
I've not had a console since the NES so this is fun new territory for me. Why did I pick the SAD? Well, I don't mind downloading the games. My connection downloads with between 95-150mb/s so it doesn't take that long. I'm quite casual, so having one of them game passes will last me a long long time. Just connect it to my second monitor and I'm off to the races.
Would I recommend Xbox One X? Well, that depends on what sort of gamer you are. Just by asking the question here, I can only assume you'll be absolutely fine with the S. I know I am. Hook me up and we could play something together. Cheers!
