I settled on mediawiki myself due to basically how trustworthy mediawiki and mediawiki skins look. I use https://github.com/CanastaWiki/Canasta-DockerCompose myself but the default includes caddy, which I just overrode in the docker compose override. I believe Canasta is mainly driven by someone who works on a wiki farm.

I also know of https://github.com/nasa/meza.

However, I want to repeat my recommendation of miraheze. When I run into an issue or need an extension, I just look at what miraheze does or what people associated with miraheze do. I also believe that due to the nature of mediawiki it’s a better use of resources to have a wiki farm as opposed to many separate instances. If they will host your wiki, I think they’re the best choice.

Do you need to host it yourself? https://miraheze.org/ may do hosting for you

My understanding is that it is only “outside the law” in that

There are no internationally agreed catch limits in the region covering squid

The law of the sea, probably / theoretically UNCLOS, would still apply. I don’t think any power would approve of anything militancy related and I think it’s likely they would take steps against any groups that are involved in anything militancy related.
