Have distro hopped over the years - most recently Manjaro to Fedora to Endeavour, but haven't found the one that's quite perfect for me.
That said, I'd make a few recommendations based on the person I'd be "marketing" to:

New to Linux, looking for polish: Mint
Mint is built off the well-known Ubuntu, polished a step further. It's in my experience the simplest to use and most generally polished of the Linux offerings. The community generally isn't as catered to power users, but if you care more about your time than about customization, I'd recommend Mint.
Looking for Stable/Modern, willing to jump thru a few hoops: Fedora
Fedora has come a long way over the years. It's far more stable, polished, and accessible than ever before. I'd hazard to call it my top recommendation, BUT, third-party software management and installation can be something of a nightmare. COPR is approximately equivalent to the AUR of Manjaro/Endeavour/Arch below, but at this time very obtuse and difficult to learn or work with. Some day you'll want a package that exists in COPR, and that day won't be fun for you.
Need apps you can't find anywhere else: Endeavour/Manjaro
Forget bleeding-edge packages and rolling release - the Arch User Repository (AUR) is hands-down the greatest feature on offer from Arch-based distros. The AUR is a repository of packages created by users that aren't supported by the main repos. If ever there's a time you need a piece of software and you can't find it anywhere else, the AUR's your best bet.
That said, I found/find both Manjaro and now Endeavour to be a little rough around the edges, and the consequence of rolling-release and bleeding-edge software is a system that isn't always working just right.
Looking to learn, straight into the frying pan: Arch
Same benefits and drawbacks of Endeavour/Manjaro above, but if you want to set up your system service-by-service, as lean as you want, Arch is there for you. A great experience if you just need an excuse to "try" putting an OS together piece by piece, even if you don't ultimately keep it in the long run.

Desktop Environments
The great DE debate. Nobody can tell you what's right and wrong here, but I have a few general breakdowns of the "big three".
GNOME: If simplicity and elegance is your style. You sacrifice customization potential for cohesion and polish.
KDE: Modern. Powerful. Usually polished out the gate. Can be a bit much if you're trying to tweak it tho. My personal choice.
XFCE: Less modern, more friendly to lower-end systems.

Whelp that's it from me, hope it helps!
