I will respond even though this post is several days old because I actually do this. I have some vpses on Hetzner that run Silverblue no problem. It is not an install option available by default there, but support uploaded an iso under my account quickly when asked.
If you do it, change the active firewalld zone. The default is for a desktop, so not great for vps space.
Hmm, docs.conduit.rs appears to be an alias for famedly.gitlab.io. I copied the link from the intro in the README.md file in the GiLab repository.
Here is the Conduit Docker deployment guide.

I started with the Docker Compose file they provide, and "translated" it into Podman rootless containers for my server. Even with adding the extra work, it was pretty painless.
Agreed on Hetzner, although I have used customer support—to add another distro option. Sent them a web link, and they had it uploaded under my account by the next day.
Nothing serious. In GNOME my alternate chars and compose were set to the same key after the upgrade; just had to change one. There was an issue with "sloppy" window focus, but they fixed that upstream before the official release of 45. I upgraded during the beta.
Librera Reader for everything. I use it for both books on a phone and comics on a tablet—covers both great! Plus it is on F-Droid.
I use Pocket Paint/Paintroid: https://f-droid.org/en/packages/org.catrobat.paintroid/
