Those are all good activities so I'd say to encourage them.
Mind was into building, using Legos or K'nex or those marble courses (ramps and so on) that can be taken apart and reassembled. Often he combined sets to create elaborate structures - no surprise that he went on to study civil engineering later!
He was also into dinosaurs and stuffed animals, and created zoos and archeological "sites" in his room and playroom.
Inside in bad weather, he did blanket forts and stuff with oversized boxes. Outdoors, he rode bikes and played frisbee and went on nature hikes, finding rocks and pinecones he'd make other stuff out of. He did a lot with neighborhood kids, making up sports and games and riding all over. I encouraged free play and team-building stuff that kids do naturally if adults don't get in the way. We did not over-schedule him with formal activities. At 8, he could choose one thing and we chose one thing (religious school). He alternated between Recreation Dept. basketball and soccer, and took swim lessons in the summer. I think it's important to let kids sample a variety of things without pushing them to be excellent at just one thing. They're not going to play in the NFL or the NBA or go to the Olympics, so it's not about expertise, just being active.
Creativity is important, so if your kid likes drama or community children's chorus, do that. It doesn't have to be sports!
