Hi, what is the recommended way to create an S2Polygon from a set of (connected) S2Cells?

I did a version of this in the python port of s2, if you still need it. https://github.com/sidewalklabs/s2sphere/issues/37

You can create a loop from an s2cellid using the S2Loop constructor. Then create an S2polygon from that loop, with the s2polygon contructor, then use the polygonbuilder with Directed XOR options and add each polygon cell to it, to create the connected polygon.
