Shakshuka with some pita is one of my comfort foods. I use David Lebovitz’s recipe
Typically for devices that require a hub, it’s because they do not have WiFi chips. Often manufacturers leave off WiFi chips because the power draw is too high for the batteries, but there are other reasons too.
The hub act as a bridge between whatever local networking protocol is used (zigbee, z-wave, BLE) and the LAN. For example, a lightbulb may use z wave to talk to a hub, the hub uses Ethernet/wifi to connect to the LAN, the LAN connects to the WAN.
In some cases, you can setup a system that controls everything locally without needing an internet connection at all. This is often preferred in the home automation space by users who want to ensure reliable access to devices.
Some centralized hubs can talk directly to many brands of devices without needing many proprietary hubs, but they tend to be expensive or require a licensed dealer to install.
For a DIY option, look into Home Assistant running on a raspberry pi
Actually I really liked The Andromeda Strain including its ending, but it had a similar let down feeling. I think it’s worth the read. See how we thought about pandemics in the 90s before we had a major outbreak in the western world (excluding HIV)
Crichton is best when he’s writing hard science fiction like Andromeda or Jurassic Park. Sphere is too science fantasy for him and he struggles with how to make it work.
Not a direct answer to your question, but I read How to be Perfect last year. Michael Schur (creator of Parks and Rec) wrote the book as an exploration of the research they did to make The Good Place.
It’s a survey of philosophy for non-philosophers and does a great job breaking down how to make good choices without being preachy.

There are some options for Pis like unraid.
Honestly though, just pick one problem you have and solve that with docker.
Beat your head against the wall trying to figure out the virtualization, volume mapping, permissions and networking.
Then start finding other problems to solve.
I stood up a homelab for media storage and streaming… and it has now grown to 30-40 applications running in parallel.
One time I was at a specialty beer and cheese shop and I saw this guy pushing a cart alone with two children. He generally looked beaten down and glum. The kids are rambunctious, he’s exhausted, wife is missing but obviously in the store with them.
He is browsing the cases, killing time waiting for his wife to come back. He grabs a small block of cheese, looks interested it and adds it to the cart.
A few minutes later, the wife returns and immediately spots the cheese block. She picks it up and screams “$10? For a block of cheese you haven’t even TRIED yet? Absolutely not.”
Then she hurled it back in the case and stomped off while he sullenly followed her with the cart and kids
