New to MacBook. Always had a gaming PC

Currently in nursing school and went with productivity in mind as well as keeping my life and schedule in order so I ended up with iPhone and MacBook for the first time in my life, as well as an iPad for in class note taking.

I miss having a gaming PC. I have an Xbox series x. As I look at what games I can play on Mac vs pc I realize I only want a pc to play games I already have on my Xbox .

What should my move be here? Is there a way for me to play my Xbox games on my Mac?

My personal research has led me to believe GeForce now is my answer? Is this correct or is there a better way?

If I have 100 mb up down internet , would GeForce now lead to me having a competitive disadvantage in online multiplayer games meaning it’s most useful for non competitive games?

I have a 14 inch MacBook Pro m3 18 gb if it matters
