We want to block outside access to the firewall, but allow FTP and SFTP access through to a specific server. What's the right way to do this?
By default outside access is blocked if you only have one WAN IP you make a virtual server for FTP/SFTP port 21 and port 22 and the passive ports range to the server IP make firewall rules to allow them ports from like WAN to LAN1

I hope this helps!
