Since you are looking mostly for the wiki part there is Dokuwiki which is magnitudes better at being a wiki. Remember, wiki is derived from the Hawaiian word for quick or something to that effect and whatever Confluence is it isn't quick.
Don't know how well it will hold up under scrutiny if black hats gets a reason to swarm over it, but unlike Confluence you can hire someone to patch the guts of it if necessary.
Edit: I have no reason to believe it is worse than anything else, I'm just pointing out it probably hasn't had so much exposure to help it harden.
I mean: ux discussions often feels like they assume users are a separate species somewhere between ordinary humans and chimps when it comes to intelligence.
I have some experience with training users and I have only given up once.
- you can edit a paragraph without locking or creating conflicts for the whole page
- it is much faster, and as far as I can see the observe–orient–decide–act loop is a real thing and should be taken into account
- much better wiki syntax (compared to old Confluence)
- trivially extensible so you can create forms and other helpers to make it simpler for users to do the right thing
- if one absolutely need it I think there exist at least one wysiwyg extension for Dokuwiki
These were sales people.
So often, somewhere right above a chimp is where some of your users are.
I would say it is very darn complete, perhaps without the syntactic linking that Confluence has. The only thing missing from it, is a very solid backup and restore method from the admin panel. The authors want users to rely on database backups and file level backups, that must be handled manually. Essentially saying "not my problem".
Just a note on this, this is something I'd like to build in eventually. It's just that each layer of our own we add upon the underlying methods increase the risk of error in something fairly critical.
A simple command-line based backup solution wouldn't be too difficult to add, but restore and admin-panel usage are more significant challenges once you get into it.
VisualEditor is an extremely good WYSIWYG interface. The wiki is able to scale well (project sites are unlikely to approach Wikipedia scale). The API is useful. Wikitext editing gives power users a lot of flexibility, though it’s not as popular as Markdown.
Access control & edit-publish workflow options may be too limited for the desires of some project teams.

One of the main things to consider with BookStack is the semi-fixed Shelf > Book > Chapter > Page structure (Where pages have content, chapters & shelves are optional, and Books can be within multiple shelves). For some this structure is limiting, For others it helps drive organization.
There really isn't that many alternatives, SharePoint maybe, but then you're just suggestion something worse.
XWiki?
Well first its interface, if a non technical user can't user the tool that's going to be a big problem. Confluence has not the best interface but still better than Xwiki. The best the interface the better the adoption as a whole in the company. And for knowledge sharing adoption is critical. That's actually why Notion has been such a success recently. Even though their product is average, people want to use it, because they like the interface.
I don't have the time to do a full comparaison of other features, but wiki tools are in usage very different than collaboration tools. Can you have the list of last consulted documents ? Can you embed external documents ? ... Kind of the same things as Slack vs IRC
That should be your first prio before anyone locks one's information into your system...XWiki can import and export confluence and even wikimedia data, i never use a system when in cant import/export to the the next best product.
Are you drunk? Who tf ever wants that?
Example: If you are a semiconductor manufacturer, you probably are not going to be storing all the documentation about your bleeding edge fabs on a cloud provider.
The last time we reviewed the Atlassian Cloud hosted products, they did not meet our security needs (requirements include isolated tenant from other customers, customer managed keys, etc) though they were much closer than a few years earlier. We also review the general security practices of the company (for example to make sure they implement a secure SDLC and follow other security best-practices).
In short, that’s not happening for a wiki.
