@Fizz @Toasted_Breakfast I had a look at a few guides. They all come with a few assumptions and get into details but I was thinking that any guide needs to cover:

options:

Infrastructure - e.g. VPS/bare metal at home ,

Applications - nextcloud, media server, home automation etc.

Middleware - identity/authentication/ reverse proxy, backup, email, Patching/updates , xdav and other support tools for mobile,

Networking - home network, subnets, vpn/tailscale, firewall, port forwarding, static ips., ipv6
