Great mentions. 
Adding the following since you mentioned Samourai, they have an eco-system of software based on how deep OP decides to go the rabbit hole in Bitcoin:
- Sentinel (Watch Only)
- Samourai Wallet (Which you already mentioned)
- Dojo ( Samourai's Bitcoin Node implementation)
- RoninOS/UI (Dojo stack rounded with a bunch of node-side tools to help manage & spend UTXOs and remain private)
- RoninDojo (Plug & Play RoninOS hardware)
- Whirlpool (coinjoin implementation, available in some other wallets also!)
