Looking for a safer way to store my Crypto

Hello Reddit! I'm looking for a safer way to store my crypto, but don't really understand the whole process.

I've currently got ~$5000 invested into different coins, and have bought and stored them all through Coinbase Advanced. I've just recently turned 16, so this is quite a lot of money for me, and although I'm okay with losing it, I would be very upset to see that I got hacked, or something in general happened where I ended up losing my money/getting it stolen.

With this in mind, I was looking into purchasing a ledger hardware wallet, or something like it, just to make sure that I am storing my crypto in the safest way possible. Only questions I have is, how would I buy/sell my crypto? Would I just purchase it through Coinbase Advanced like I already do, and then send it to my hardware wallet? Or is there a different way for me to buy and store my crypto, that would possibly negate service fees and just all around get rid of having to go through exchange services like Coinbase, Kraken, etc?
