XBOX S OR X?

I currently have an Xbox One S 1 TB and to be honest I've never fully utilized it in the past six years. I only play FIFA whereas my brother has started to play it on a daily basis (Skyrim). I recently bought a Game Pass Ultimate for the first time and tbh I'm loving the experience of downloading and playing digital games. Now, I'm plannig on buying the newer Xbox, given that we're not hardcore gamers and like the digital experience as well, should I go for the Xbox S or Xbox X?
