I don't know about sports games. I am getting ODD also 10 and YDD a switch. We all play video games. A lot are available on the computer, and we mostly play on there. However YDD and I love Zelda and Mario so that is why we do Nintendo as a console. ODD mostly plays on the computer - Minecraft, Overwatch, Stardew Valley, but she likes Mario stuff and the dancing games.
My advice is to decide what games you think he'd love and see what they are available for. Hopefully that will help narrow your choice. I will say that if you are not doing games on a computer and only plan to have one console Xbox or Playstation might age better as he gets older...for us, we use the computer for gaming and the Nintendo as a supplemental gaming device. TBH it's mostly for Zelda.
