Its likely the friendly words will continue but the EU will delay Serbia joining.
The EU is dealing with Hungary already, plus looking with concern at whats happening in Slovakia.
Serbia won’t be joining the EU any time soon, and the EU will string Serbia along in the meantime watching what happens. They won’t want any more authoritarian regimes joining. Hungary is already a huge thorn in the aide of the EU.
If youre new to linux, then I’d say Linux Mint is the place to start. Use it with XFCE if light weight is what you want.
Not having cutting edge packages is a red herring - you really dont want bleeding edge as thats where the errors and breakages happen. Mint is reliable and secure which is what you need when starting out. You dont want to be a beta tester. Dont confuse latest packages for most secure on linux - plenty of packages have stable older versions which get security patches.
Mint is also very popular, with a huge range of easy to find resources to help set it up the way you want it.
Wayland is also a red herring - its the future but its just not really ready yet. Yes its more secure due to how its built but the scenario you’re using linux in the particular security benefits you’re hearing about are not really going to impact you day to day. And the trade off is that Wayland is still buggy, with many apps still not working seamlessly. Most apps are designed for X11 and x-wayland is an imperfect bridge between the two. I’m not saying Wayland is bad - it’s actually good and is the future. But you dont want to be problem solving Wayland issues as a linux newbie. Dont see Wayland as essentialnfor an good stable and secure linux install.
Personally I wouldn’t recommend Fedora - it has a short update cycle and tends to favour newer bleeding edge tech and paclages. Thats not a bad thing but if what you want is a stable, reliable low footprint system and to learn the basics, in wouldn’t stray into Fedora just yet. It has a 13 month cycle of complete distro upgrades and distro upgrades are the times when there are big package changes and the biggest chances of something breaking. The previous version loses support after a month so you do need to upgrade to stay secure. Most people won’t have issues between upgrades but with any distro when you do a big upgrade things can easily break of you’ve customised things and set up things differently to the base. It can be annoying having to fix thongs and get them back how you want them, and worse can lead to reinstalls. Thats nor a uniquely Fedora problem, but the risk is higher woth faster updating and bleeding edge distros. And in fairness there are lots of fedora spins that might mitigate that - but then you risk being on more niche setups so support can be harder to find when you need it.
For comparison the latest version of Mint supported through til 2029, and major releases also get security patches and support for years even after newer versions are released. There is much less pressure to upgrade.
