Guys, totally new, I need 3 ports to connect to different things from minipc how simplest way?

I just bought one of them minipcs off of some asian site. Going to use it for pfsense here with 3 ports going out to main computer, another computer and maybe a vonet wifi or extra ethernet of sorts.
I understand I need to configure these ports so how would I do that simplest way, I don't want them talking to each other but be isolated from each other so if one computer/phone is hacked they can't reach another computer.
I won't be using any VLAN switches just the ports directly from the minipc that has the pfsense in it.

First I install the pfsense... then...? Do I set all this up in the pfsense GUI and so on?

You should start here: https://www.pfsense.org/getting-started/

To allow access to the internet only, best practice is to only use private IP ranges (RFC 1918) inside your local network.

Then create an alias of type network and add all RFC 1918 networks to it. Then use this alias as destination in block rules on all internal interfaces.
However, if you use the DNS resolver on pfSense, consider to allow access to it with a pass rule above of it.

Yes. At the first boot after install you would assign the NICs to interfaces at the console. Then connect to the webgui on the LAN interface and configure the other interfaces.
