A single statically linked binary would not raise the barrier of entry. Quite the opposite.

What if you're running on an ARM VPS? Now there are 2 binaries. What if you're running e.g. Alpine? Now you need 4. Which init system do you provide startup scripts for? You need an install script too. And what if you just want to try it on your Windows/Mac computer? Need to manually set up a VM.

Meanwhile, you can just install Docker, which you might already have if you do self-hosting often, and run one command. The overhead of containers is tiny, so you really won't notice it. Bonus points for using Podman, which doesn't even have a daemon.

But you also need to provide a systemd service for it. And statically linked against glibc or musl?

you need to provide a systemd service for a docker image as well, the restrt policies leave a lot to be desired for a host that itself can restart.

glibc doesn't support static linking, so it's probably going to be musl. Running a musl binary on an otherwise glibc system isn't an issue.
