Below I have listed some resources that I have found useful in my own Bitcoin journey. I trust that you will find them helpful.
Where to Buy Bitcoin
Coinbase/BISQ
I used to recommend Coinbase as this exchange was a great place to start for people completely new to Bitcoin. It is where I began my journey some years ago and it offered a great user interface that was easy to navigate. I always advised against storing your coins here though. In these troubled times with a number of crypto exchanges starting to fail, it is more important than ever to learn how store your own Bitcoin where no one can take it from you. For this I recommend that you need a hardware wallet as demonstrated below. The best way to obtain Bitcoin now is from a decentralised exchange that facilitates the purchase of Bitcoin peer to peer. The best platform that I know of at the moment that avoids the exchanges is BISQ. There is a link to Bisq below and I will be producing a video explaining how to use Bisq in the very near future.
How to Store Bitcoin
Trezor
Once you have purchased your Bitcoin on an exchange, it is possible to keep them there, but not recommended long term. In order to hold your Bitcoin in your own possession and under your own control it is advisable to store them on a hardware wallet. One of the best known brands is Trezor. The link below takes you straight to the place where you can buy one!
