The book “I will teach you to be rich” has a great overview of how to best leverage credit cards, high yield savings accounts, setting up automatic investments, saving, and lots of other ‘good to know’ topics about money.
For investing specifically I use the Boglehead method.
If you’re looking for a more mature networking setup, I would definitely recommend splitting up your router, switch and AP duties into separate devices. It gives you the most flexibility for when you want to tinker or change things.
For a main router setup, I would recommend OpnSense. It’s has a cloud backup feature which allows you to automatically backup the configuration to a Google Drive xml file whenever it is changed.
The XML config file stores all your leases so you don’t have to worry about reassigning DHCP reservations. If you load the config onto a new system, like for an upgrade or if the router hardware fails, usually you just have to change the interface mappings and you’re good to go.
As far as APs/switches, I would recommend Unifi or Mikrotik. Unifi has a fancy dashboard you can use to adopt new equipment and restore/change configs from, but I find Mikrotik easier and simpler to backup and I like that i dont have to host a controller to make config changes.
