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!)
