You are asking too much :-) Essentially you are looking to setup a "Private Cloud" with the required services on your own hardware in your own "Homelab" location. So you have to approach it top-down i.e. a) What services do you want? b) What are the SW and HW involved? c) How are they put together? d) What solutions/frameworks are already available for the above? You start by reading up on "Cloud Technology/Architecture" and understand terms like IaaS/PaaS/SaaS and how the three fundamental cloud resources i.e. Compute, Storage and Networking are virtualized in the above layers. Any cloud tutorial/book will give you a good overview. I can recommend Cloud Computing for Science and Engineering by Ian Foster et.al. (https://mitpress.mit.edu/9780262037242/cloud-computing-for-science-and-engineering/ https://mitpress.mit.edu/9780262037242/cloud-computing-for-s...). Now you should be able to understand products/Jargons like GitHub/BitWarden/Tailscale/FreeNAS/VPS etc. and where they fit into the overall picture. The final step is to buy the hardware and go to town installing/configuring services.
