I’ll drop this: https://www.techradar.com/best/best-linux-distros It’s written by an actual journo and not a bunch of nerds in nerdville!
Getting into Linux is a bit like Windows back in the day - interesting and a lot of fun … and rather nerdy. My first Windows version was 1.0 and my last was 7. Mind you I do run a MS Silver Partner and worry about a lot of Windows servers and desktops but my daily driver is Linux.
Mint is a great choice, even though it isn’t mentioned in the article I linked because you get a great community, which is pretty important. Its basically Ubuntu and therefore Debian too, so a lot of howtos will work.
I personally rock Kubuntu but I have a requirement for enterprisey stuff - ESET and Veeam and AD integration and all that. I also get Secure Boot out of the box and not all Linux distros work with that.
Your smart new laptop will have Secure Boot enabled so you will have to deal with that if you deploy a distro that doesn’t. So with say Arch, you will need to turn it off or learn how to sign your kernels etc and that is not a beginner topic! I suggest you turn off Secure Boot if your chosen distro doesn’t support it, rather than insisting on it. Its a nice to have but not the most important security feature ever.
You might want to show a bit of ankle and try out a few to start with. Most distros have a live CD that you can boot and try out first. I suggest trying out Mint, Ubuntu and Kubuntu. That gets you three modern interfaces to play with.
If you are into gaming then it kooks like Pop!OS would be a good place to start instead.
There is no real best option - it’s what suits you and you have choice.
ip eg:
# ip a # ip a a 192.168.1.99/24 dev enp160
The first incantation - ip address (you can abbreviate whilst it is unambiguous) gets you a quick report of interfaces, MAC, IPs and so on. The second command assigns another IP address to an interface. Handy for setting up devices which don’t do DHCP out of the box or already have an IP and need a good talking to.
Oh and you can completely set up your IP stack, interfaces and routing etc with it. Throw in nft or iptables (old school these days - sigh!) for filtering and other network packet mangling shenanigans.
