Good CS classes for getting into software?

Hi I’m a EE major but I’m picking up a minor in CS and also have a swe internship for this summer. I’m basically making the switch over to software and was wondering if anyone had good class recommendations for getting into it. Next semester I’m already planning on taking CS 225 and Ive already taken ECE 391, so besides those any class recs for someone trying to get better at software would be appreciated. Thanks!
