Buy with Bisq/robosats.
Store with coldcard, passport, seedsigner (not exhaustive, just the ones I've used that I like). Backup the seed in multiple places and consider spreading info so its not all in one place (such as via passphrase, seed XOR, or border wallet).
Monitor with Sparrow (desktop) or Nunchuk (mobile).
Also recommend connecting to your own node or electrum server.
