I feel like it's likely that we'll see some loose connective tissue, if nothing else - "hey, this thing previously established in the Litverse doesn't contradict anything, we can bring it forward."
With regards to the novels proper, it does seem like, with regards to TNG, DS9, Voyager, and probably Enterprise (since it seems that Rise of the Federation is going to be wrapped for the time being), we are going back to standalones, but that's not a bad thing necessarily - personally, I have been waiting a long time for some novels to sort of "rehab" season one of TNG, for instance, smooth out some of its edges in terms of how it connects to the subsequent continuity, so there's room for such a thing. Likewise, I think there really is a level of comfort in getting to revisit the times we know and are familiar with most and have a new adventure.
Plus, as we're seeing between Shadows Have Offended and Revenant, it's also opening the doors to let some new voices into the franchise who there wouldn't necessarily have been room for in the time of ongoing post-Nemesis novels. And that right there seems like something that NEEDS celebrating - not in any way a slam on our regular line-up, but it HAS been lacking in diversity in the writers over the last few years, and that's just not in keeping with the Trekkian ethos.
So I wouldn't expect to see any novel-only series for several years, minimum - as long as the spotlight is going to be on the in-production shows, probably any new idea and focus would be put on the shows, rather than the novels, since the job of tie-ins is, effectively, to supplement the shows, not to "take the spotlight" or anything by doing things that could just as functionally be on screen. Y'know, it was 1997 when New Frontier began, DS9 was in its fifth season, Voyager its third, First Contact had made it to home video... It took a while for what was the height of 90s Trek to reach the point where they let a novel-exclusive line begin, and while I'm sure that, with that history in favor, it probably won't take as long to see another new novel line begin, that one day there will be another series originating in the novels, it's going to be some time as the shows keep going. I mean, they're holding off on the active production of the 31 series to avoid the risk of oversaturation, so that's clearly something that's in the minds of the heads over at Paramount/CBS.
We might not see as strongly connected ongoing stories within the novels as we've been used to, but I think it wouldn't be wrong to expect something like the small scale stuff we got in the Discovery novels, where they were expanding, growing, and connecting Discovery into the greater tapestry - now we can see that returned by having things established in 2010s/2020s Trek appear in the settings of 1990s/2000s Trek.
Y'know, we had The Enterprise War referencing various versions of Pike's Enterprise from across the years that have tried to fill that gap and more or less contradicted one another. I'd believe there being similar kinds of welding in store in future stories, things that will show how these events echo into the future.
