I got medicated as an adult, so I can't directly share my experiences relating to your question.
I wish I had been medicated at a younger age, since I can see so many problems I had in my life that were ultimately related to entirely unmanaged ADHD.
I also turned out fine without it, things were just more difficult.
Make sure you trust your pediatrician and that you're on the same page as them. That'll make it easier to feel confident that their advice is in line with your goals. They all have your kids best interest at heart, but there are different emphasis they can focus on which might not mesh with yours.
Talk with your kid and see how they feel. They might not be old enough to fully articulate things, but you can try to get a feel for if they're feeling volatile, struggling or things like that. Look at how they play alone and with others, and at how they engage with homework.
Start slow, and work your way up.
