XFCE is very stable so it should work almost exactly the same on every distro. Just pick the one that you like the most / is easier to install for you / etc. KDE is a bigger and more complex system so it works a bit differently depending on what distribution you use. Some distros like KDE Neon always have the most recent KDE while other like OpenSUSE Leap prefer to use stable versions of the applications. When it comes to wifi/sound/etc it has to do with whether the driver for that contains binary blobs. Some distros don't ship blobs due to security and/or software freedom concerns while other distros have a more relaxed policy when it comes to proprietary software. Thinkpads have a reputation for being very easy to run Linux on. You should expect everything to work out of the box. For the Dell computer you might have to install drivers separately but you can't tell for sure without knowing the exact model you have. You could do a test drive with a Live USB to check out. I wouldn't expect things to work out of the box on the macbook though. Apple isn't very Linux friendly and their macbooks have many specialized components that are only found on Apple products so Linux support is not very good. But even then, some dedicated hackers still try to reverse engineer them so you might have better support if you have an older model instead of the latest macbook.
