I would assume that Starfleet Academy is one of the two, and it fits with the CBSAA approach of all the shows being different to each other. I'm really curious as to when they would set this, though. Personally, I think a series set at the dawn of the Federation, when the academy is suddenly seeing an influx of alien species', would be the best time. I'm not sure what we'd gain from seeing it in any other time period, but I'd love to be wrong.
I'm not convinced that Pike is the second series, nor that we'll even get a full series focused on him. For me, Pike is only going to get either a CBSAA movie, or a mini-series. I'd rather the TV movie format, personally. Let's spice things up.
For the second live action series, I'd really be keen on what others have suggested: a political show, based around Federation politics. I guess that Picard is delving somewhat into that area though, and Discovery seems to be, too, so perhaps there's not so much to mine there.
Who knows, maybe the second show is based in Discovery's new time period, as they look to flesh out that era a bit more. Or, as was once often suggested, a 29th century timeship series.
