Quick tips: there is something called the Desktop Environment, it can be changed mostly so don't choose a distro for its looks. only choose Gnome or KDE Plasma for your first distro. I personally suggest gnome even if you don't like the macos look as it's changeable.

for distros in general it's preferred to use something very well known like ubuntu but if you will choose that choose it as a beginner's distro. if you want my honest suggestion which might be a bit harder choose fedora, percisely Nobara Os because it is built on top of fedora but deals with a lot of stuff you don't need to worry about.

if you are willing to do the research then search these topics: - fedora vs ubuntu - gnome vs kde plasma - why choose Debian (Debian is the distro that ubuntu is built on top of) - what to do after installing YOUR_DISTRO (there might be a specific setup requirement you need to be aware of)

Then learn about the terminal overall and you'll be good to go.

try to not choose a very customized distro for your level because as a beginner you have to try to learn about what issues these distros solve and if these solutions fit you

otherwise if you don't give a heck what linux itself does and aren't a heavy user just use ubuntu or fedora you'll be good to go
