Ardour is great, I suggest you to learn it even if you want to use some other proprietary ones, since it have an useful tool for fast mastering with setting optimized for social platforms. I also suggest you to use great floss plugins like SurgeXT, LSP-Plugins and Geonkick.










The flatpak version is a little tricky to setup (directories) so I suggest you to use the distro pkg. "Unfa"on youtube has great tutorials. Ask me if you need something specifically.
