We've ditched Wordpress and are now running Jekyll. I tried Hugo but I couldn't get it to do what I wanted easily. I still had to make some consessions with this site, but nothing that I can't work around. Everything is now static generated everytime I push a post to the repository.
I will slowly work on getting the original content over to the new site. I will likely be archiving the old site in some fashion as well. I have everything exported to Jekyll, but I have a lot of manual editing and checking to do.
