How do you give your players meaningful choices while also handling a story?

I am in the mid stages of prepping my own homebrew campaign for my friends and the one thing that’s always on my mind, (which could just be pre campaign stress to be clear lol) is how can I give my players choices while also keeping the story going & not railroading them? I just want to make sure that their choices can matter but I’m not sure fully how to do it correctly. I hope this makes sense.
