In fact, many college students have this problem. I was also the student union minister in my sophomore year. According to my experience, the work of the student union does help to cultivate our ability to deal with affairs and social interaction, but it doesn't mean that everything it gives you is meaningful for your ability training. Some abilities can be learned in a short time, while others can be acquired through other channels. Students' union is not the only way to exercise their abilities. Don't be too superstitious, this is one of them. Second, as you said, you still want to have your own private time, running and reading, so you need to manage your life, allocate your time reasonably, and don't be bound by some trivial things. Many activities of the Student Union are similar or even repetitive. As long as you have the ability to exercise and the interpersonal network is established, then the purpose of joining this organization has been achieved and it is time to retire. As long as you have served as a student union cadre in college and you really have good working ability, you can write down your post as a cadre when you look for a job in the future. The point is not how long you have been a cadre, which is also good for you to find a job, you know?
