Back in Feb last year Kurtzman was talking about how they wanted shows developing for airing 2-3 years out. Discovery's final season is coming during broadcast this year, meaning you're looking at something filling in the 32nd Century slot in 2024/2025. Of these, that we know of, there is Section 31. Which repeatedly gets delayed because Michelle Yeoh is, quite sensibly, continuing her career while they play grab ass on how to write it. She left Discovery 2 years ago now and seems to be getting plenty of work.
A cheaper small scale show to continue showing off the 32nd Century would logically continue to be the Academy series. It also seemed to be heavily hinted at in stuff like Empire Mag and suchlike last year the Academy was becoming the most developed of the ideas they had in stock.
We're probably hearing more about a continuation of Picard because, ya know, the show's airing right now so of course discourse is "what's next with all this lovely set up?" Matalas just outright saying he wants a Captain Seven show and has apparently been pitching the concept for a little while, is also going to guide conversation that way.
