Yeah that works. I've done piano, jujitsu, hockey, and half a dozen other things with my kid. If they ask to do something I let them, but make them do a commitment. If they hate it, they can stop when the season is over and try something else. The tricky part is to balance ensuring they learn not to quit just because something is hard, with not making them do something for too long that they've just figured out is not for them. Piano and gymnastics were a big no, while they fell in love with the right jujitsu gym.
Not everything has to be competitive or official either. Like you can just go to the community pool during the summer without joining a swim team. I think some parents forget this, but this was normal for previous generations.
So my kid has a few extra curricular activities and then I also do plenty of activities with them at the house like play chess or card games or whatever. They're also watching some of my old favorite sci-fi shows with me. Nearly all of YouTube kids is steaming garbage designed to turn your kid into a mindless consumer. Netflix kids is pretty good though. There are a lot of shows that have character progression and multi season plot arcs that cover complex subjects. Avatar the Last Airbender is an example of a show I was comfortable with my 7 year old watching without worrying about brain rot. Mind you, I think all screen time needs a limit.
