The ressources given would depend on the amount this person is looking to buy medium-term, and their technical level.

Along with the ressources, a good wallet is primordial.

-Play money/discovering Bitcoin : Wallet of Satoshi

-Some money/Diving into the rabbit hole about bitcoin : Green Wallet from Blockstream (nontechnical), or a Coldcard if they want to play with a hardware wallet.

-Serious money/Life Savings : If they're technical, a multisig setup with coldcards/tapsigners/etc. is great.

If nontechnical, nunchuk is also great, or casa as a last resort.
