I've been looking into NextCloud to recommend to a government agency. The world desperately need competition or at least something compatible with the m365 stack, because it's eating the world and taking a lot of choice away and killing a lot of innovation outside the Microsoft funnel, since Microsoft is not interested in a lot of tech (for example, network schemas, useful for "tell us once" type applications, since they'd rather you just use their tech for everything, and the messier it is behind the scenes, the better for them).
Anyway, I have mixed feelings. I admire the community and the support it has by many governments, its staunch Open Source basis so it's useful for an individual or a large organization. But it is building on a lot of crufty PHP, their collection of apps is very uneven and it's hard to know what works well without a lot of research, and it's going in a few directions to upgrade. AppApi in particular is on one hand very innovative, on the other going in some odd directions. I know it is successfully used by very large organizations, but without spending a lot of time with it, it's hard to get a sense of the commitment and considerations required.
I think more than anything they need advocacy and good quality product contributions (support, documentation, code). From what I know, a lot of the development happens via a few consulting firms that support their larger clients.
