We did a great hike in Skagway on our own that the NPS recommended called the Lower Dewey Trail to this beautiful glacier lake. Highly recommend that. And if you want, you could keep going to upper Dewey Lake, which was too much for me!
For Sitka, I second the walk out to the totems and then you can keep going all the way to the brewery. They have local taxis that can bring you back, unlike some of the other ports. The Raptor Center is on the way to the brewery if you want to add a stop. Not super strenuous but beautiful. It was one of our favorite ports.
