Most government deployed websites do not use Cloudflare. I don’t think they choose a different outsourced competitor; they likely insource admins who are proficient with web security.
Some admins use Cloudflare DNS but not the proxy. This enables them to be able to simply and quickly flip a switch on-the-fly when the load exceeds a threshhold. That can also be scripted to happen automatically. Then visitors are not burdened by Cloudflare most of the time. Some admins also know how to configure CF to not block indiscriminantly, but I think that control only available to whitelist the Tor network not the other groups who face discrimination.
Indeed. I wasn’t sure if tja was asking for alternatives for admins or users.
Sometimes the marginalized groups of users can circumvent Cloudflare by finding an archive.org mirror of the blocked page, but that does not always work (and if interactivity is needed it never works). There is a browser plugin which will detect when a user clicks on a Cloudflare link and automatically redirect to archive.org.
