What a brilliant clearout you've had!
To be honest, I'd wait a little re the patios to see exactly which bits you'll use most. I speak from experience - in a previous garden we built an extension and then created a raised deck right along the back, with access from the new French doors and steps down to the rest of the garden. Ideal to sit having breakfast, lunch, a cup of tea etc. Where did I sit most? On the steps...
It was the best bit - private and warm and in the 'middle' of the garden.
If you use the one at the house most, I think I'd repair that so that it's really smart, and if you really want a seating/dining area half way, you could create something smaller there next year. In the meantime, put a couple of chairs and a small table in that spot and use it to see if it will work long term. Draw a plan - doesn't have to be exact - and sketch a rough layout. Making circles work effectively can be tricky - you need to be sure of that everything will link well with all the rest of the space.
