Signal is to privacy what duct tape is to a broken item - it solves your issues and concerns, but you shouldn't expect it to last. Instead, consider Matrix.
It depends on what hardware you host it. Most people can’t affort powerful hardware. My experience with self-hosted matrix on a raspi 4 and on an old desktop pc hasn’t been great, and the problems grow with the number of users
In my experience, self hosted matrix is way faster than matrix.org ^^
