Add underground plumbing to #5. You may have a pipe or duct that goes through or under the footing to consider before the footing goes in.
Framing should include osb sheeting. Siding needs to wait on the roof to get your soffits, etc to come out and can be done anytime after the roof goes on and while interior work goes on.
Move roofing to #8. Get it covered asap.
Add Plumbing rough-in and electrical rough-in to go with HVAC rough-in and mechanical rough-in which can be done as the windows go in and even as the roof gets covered. Do before insulation and drywall.
Flooring depends upon type but can be done during or after rough-ins.
Never heard of title 24.
Good luck and talk to your subs as you may have a lot of lag time waiting on their schedules.
