Linux

Just a minor suggestion. When looking for something different than what you're currently familiar with, do so in very open minded way, hopefully no looking for clones to what you were used to, but willing to experience and learn new stuff (there's no failure, just something new that had to be learned and experienced).

I know it's easier saying than doing...

Looking for advice on giant communities is sort of hard, and in the end you won't know what works better for you if you don't try it. The open mind needs to come with some time to be able to play, and enjoy during the play, so it's not a whole series of frustrations.

On this same forum (different threads/posts/converstions) I've read very different recommendations. Even though Manjaro has been recently getting a lot of bad reputation because of letting some certs expire, it's still considered an "introductory" gnu + linux distribution. I've also read Mint is a pretty good "introductory" gnu + linux distribution as well, specially now that ubuntu has finally shown its inclination towards its snap store, rather than the good and solid dpkg + apt, which allowed it to grow on users to where it's currently at.

I myself prefer rolling release models for distributions, and being as vanilla as possible, to be closer to upstream as possible. However I dislike systemd, which is just a personal taste, so I don't have a specific recommendation. It used to be Manjaro offered openrc, but they dropped it, and the distributions I know are Artix (it has gui installers if that's considered "introduction" level distribution, but one still need to handle the configuration mismatches with upgrades as with Arch), Gentoo (I wouldn't say it's not for starters, but for sure it has its learning curve, but more importantly you need to be aware that it's a source based distribution), and Void. If you don't really care, rolling release distributions, which might have an easy ramp up might be Manjaro as mentioned, and now I believe openSUSE Tumbleweed. maybe even fedora come close... Rolling release models might come even easier for newcomers, in my opinion, since there's no need to think on what happens on major updates, but rather one needs to keep updating periodically, but hopefully the distribution helps supporting the safest and saner configurations natively so the user, and particularly newcomer to the distribution don't have to deal a lot to get such safe and sane configurations, at least to start with. And that's to me the important part to call it "introductory" distribution, easy installation might be part of it, but it's hardly the majority of it, and this is perhaps the sad part of what I like about being as vanilla as possible, some distributions even take that as a mantra for configurations, and upstream developers don't always have the safer, or the saner configurations by default. I believe Manjaro and some others take that into account to make things smoother to start with. Maintaining the distribution, keeping it up to date, being able to install stuff, has it's learning curve, no matter the tools/frameworks to do so, and it might be harder if one has to deal with how to make things work because the software doesn't work as it should (configuration required upfront), and it's not hardened enough as well so the user needs to know that and do additional configuration upfront as well.
