If you have a VLAN capable switch and appropriate network card with the right drivers, then you can have all the logical ports you could possibly want.
I have done this at my parents place with a cheap Intel Celeron based computer with a single network port, but 2 logical networks with vlanning. One is for their personal network and the other is for their guest suite they offer through Airbnb.
It’s only 20MB/s fibre, so not much cpu power needed. The no name computer cost less than $250, came with a 60gb SSD and I put pfsense on it.
