Is the 105 R7000 compatible with electronic Di2 shifters?

No — the RD-R7000 is a mechanical derailleur designed for cable-pull operation. Shimano Di2 electronic derailleurs are separate products (RD-R7150 for 12-speed).

What cassette should I pair with the RD-R7000-SS?

The short cage SS version is optimised for cassettes from 11-25T to 11-30T. Popular choices are 11-28T for general road riding or 11-25T for flat racing. For anything larger, use the GS version.
