Nope. Several questions. :-) And there are no stupid questions, just
stupid answers. :-)

You could bridge it and make it a switch, or you could route it and do
filtering, and other cool stuff.

Yes. But not necesarily feasable.

Complexity, troubleshooting, and cost. For you, cost is almost a non-issue,
but still there.
> Is this about bridging?
Could be. A switch is a bridge. A hub, is a hub. It has to do with arp
lists and broadcasts.

Unless the NIC on your laptop is autosensing MDI/MDIX, yes.
