It’s focus may be rdp, but it supports SSH connections just fine. I switched my main driver yesterday from Windows to Debian (Cinnamon). I came out looking for the same thing as OP, Remina fitted right in as an SSH connections manager

If you are using the *arr stack, Bazarr may be what you are looking for.
