> what do I start with as a base OS these days IMO, there are two primary options: — Rocky Linux (or AlmaLinux) if you prefer a “bit more corporate” flavor after getting used to Windows; — Debian if you'd like to get “more community” one. Once you're somehow familiar with one of these, you should be able to figure out what else you may want to try.
