If you are a little keen on learning the ins-and-outs of Linux, I highly recommend staying with Fedora. In my opinion, it has a great balance of stability and cutting-edge software selection in its repositories. The problems you have outlined are due to the default desktop environment choice of GNOME in Workstation Edition. The developers of GNOME are kind of perfectionists and have their own vision of what a desktop environment should be like. This often leads to having some common functionality most people want missing, at least without community-made extensions. KDE Plasma, on the other hand, is quite receptive to feature-requests and has all the functionality you mentioned, while being just as well supported development-wise.

UFW, by default, blocks all incoming requests. This means that SSH (port 22) is blocked already. Then, if you need to, whitelist (ALLOW) ports that you want to expose to the network. For example, I have ports 1714-1764 whitelisted for KDE Connect and everything else is blocked.
