To start with the question: What makes sense to you?
If I may I’ll share my own journey of 10 stages (and it works well for me):
4. Bar between Handle-bar and seat
9. Front wheel
10. Fence (where I usually chain my bike to)
Do you notice: it is a ‘natural’ sequence starting at the front and going around in a kind of circle.
Now: give it a go yourself!
