Paramount+ is the place!

For physical media, I noticed I could find all the films and the first season of Strange New Worlds in Ultra HD at Best Buy.

I also find entire collections on DVD and HD (non 4K) Blu Ray at used places like Zia Records (the only national chain I can think of) and other similar stores with used movies.

(Edit, that other deleted post was me, but from the instance admin account, which I don’t use for external things. Whoopsy!)
