Does fedora set firewall by default or have an easy gui like linux mint’s gufw where I can deny incoming and allow outgoing? Do I need to worry about firewall on Fedora?
firewalld should be running by default. Last I checked there firewall on Fedora was extremely permissive.
You may want to use the firewall GUI to tighten down the incoming allowed connections.
See: https://docs.fedoraproject.org/en-US/quick-docs/firewalld/. You should check systemctl status firewalld and also check that the settings are appropriate for you, e.g, using firewall-config GUI or firewall-cmd --list-all in a terminal.
