I get the feeling, but in my experience it has more to do with the windows UI actual getting worse. When I use Linux, I’m happy to try out different desktop environments and shells, but they have one thing in common: they have designs that are created more thoughtfully.
It’s not just us growing old, it’s the world of technology growing shittier too!
Just start with Linux mint and cinnamon or kde desktop environment. You should be good to go with that. Kernels are not something that you usually need to worry about, the default should work fine. If you need to, it’s easy to switch to another kernel by just installing it through the package manager.
