I would take the whole thing out short of the side up against the house and put a decent wood picnic style table, a fire pit (if that’s allowed where you’re at) like one of the steel ones raised up off the ground and use the extra space for growing veggies and stuff.

Depends on what you want though.

Are you wanting to repair/replace it and have that whole patio area or are you willing to do a bit more with the earth underneath it?

You could always do like you said and use pavers or gravel some of the area too and still reclaim some of the ground underneath to use for other stuff.
