Linux

You need to first understand what kind of interaction you expect with your OS. For this, you can start by considering what you use your OS for and currently what you do for your OS. e.g. Before I jumped to Linux, I was just starting to learn PowerShell on Win, because I saw a lot of places in my system where I wanted to use it. I felt consistently dissatisfied with the lack of things I could just tell the system to do, making me go to scripting. This way, I knew I won't have a problem with putting time into something that takes a lot of configuring. But since I was still new and wanted an easy start, I went with Manjaro KDE. It was based on Arch, but had a system of differed updates, giving me a feel of it being easier. Plus, it had a lot of customisations out of the box, some of which, I learnt from, when making my own configurations for EndeavourOS. EndeavourOS considers itself to be more terminal oriented, and it is possible to easily get a full-fledged tty system, just by selecting it in the installer. I chose KDE because I like changing the Appearance a lot, but you might want to look at other DEs depending upon your expectations.

Ubuntu has been shifting a lot to snaps, so if you want your computer to be snappy (the literal meaning), you might want to avoid it (ironically). But at the same time, if you want less configuration requirements and want to keep most of your exp outside the terminal, on top of finding it easier to install software from vendors' websites, you can consider it. If you are fine with putting in the minimal amount of brain usage it takes to understand the installation instructions of the website - and by that I mean, read the heading telling you which distro the copy-paste text is meant for (I know ppl too lazy to do that and trying paste an apt command into Red Hat) - I suggest Fedora/Linux Mint and a slew of others.

DE = Desktop Environment apt = Package Manager (kinda like an app store on terminal) used for Ubuntu

P.S.: If you choose an Arch-based distro, make sure you keep a backup OS that is in the Debian/Fedora tree. I keep a Debian KDE, mainly for older linux games, which ask for packages that have been long removed from Arch, but it is useful in case you break something. That way you won't have to wait for the time it takes to make a Live USB and can just restart.
