Nice hand list of utilities and services. I've been on the fence about start 9 for a while thinking if I should building or buying.
Start9 is very simple for the fact that you already have everything ready to download. There are even more user-friendly options like Umbrell, but it's not too focused on privacy. If you want to learn the whole process you can start with a raspberry pi4 or 5, although it won't be a big change either. Anyway if you want to do it all yourself, I recommend you take a look at these two websites: https://darthcoin.substack.com/p/bitcoin-private-banks-over-lightning https://minibolt.minibolt.info/bonus-guides/bitcoin If you have any question just ask. I will be glad to help you :)
