Honestly, it's hard to know what really fits your family until you try it. I think you have a good basic plan now, and it helps if you have a Plan B in the back of your mind in case you find things need adjusting.
Our touring style has changed a lot over the years. When DS was a little, we would rope drop, schedule a TS in the middle of the day for an AC break, and then leave the park early and do dinner back at the resort. Somewhere in the middle years, I think we had a trip with long days mid-day breaks. Once FP+ came along, and we had a teenager, we tended to just start later and stay later. Now it's a mix, depending on ADRs, etc. Sometimes we all go in the morning, leave mid-afternoon, then DS and I go back in the evening but DH doesn't.
Throughout it all, we would divide our plans into "must do", "would like to", and "maybe we'll get to". - For each park, we would hit everyone's one or two must-dos (be it ride, attraction, or restaurant) and then as many of the secondary and tertiary things as fit nicely around those without stressing us all out.
