You don’t mention what level of expertise you’ve got for this, or if there’s anyone you can reach out to for assistance. I think guyman384’s advice to treat this as two projects (wiring infrastructure, the server(s).

You didn’t mention how many floors to the home. If it’s a single floor, I suspect 2 AP’s will be sufficient. If you are planning to do something like Plex, have a desktop computer, or a networked printer, consider running Cat5/6 connections to where ever those will be located. For the nextwork gear, I can highly recommend the TP-Link Omada kit. I use it at hoe, in part becuase I do the network management at work all day, and want something that will just work, but give me a high degree of control. Ubiquity is popular in this space. We use UBT at work, I like the Omada better. I have a small fanless PC that I’m using to run pfSense. PfSense is good because the defaultr config works well, but then you can make the install more sophisticated as you learn.

With regard to the server environment, I’d like to hear more about your use case. My go-to response, though, would be to plan on purchasing a Synology NAS, and use the old PS for delivering Plex or some such. Especially true if you have multiple PC’s in the home, or a diverse OS population (Windows, Linux, Mac)
