Bitcoin only. Everything else is a scam. Others disagree and I'm sure they'll swoop in you shill their garbage to you, if you go down that path then good luck.
As far as wallets it depends what you're trying to do. I'll go through these is ascending order of how I would suggest.
- If you want something brainless and don't care about holding it in custody yourself something like CashApp or Strike will get the job done.
- Next is mobile wallets, with these you're holding they keys yourself in what is called a "hot wallet" which just means its always on an internet connected device. BlueWallet, AquaWallet, or something like SamouriWallet.
- Desktop wallets are IMO a bit better than mobile wallets but still considered hot wallets though. I prefer Sparrow but Specter is alright.
- Finally you have Hardware wallets, these are called "cold storage" because they're never connected to the internet. Examples are ColdCard, SeedSigner, and if you insist on coining Trezor is probably your best bet.
There are plenty of other options and there are features that not every wallet here supports. Samouri and Sparrow support mixing, Aqua, BlueWallet, Strike and Cashapp are probably the only ones here that support Lightning natively, etc. If you're just looking to store a couple hundred bucks and want custody grab a mobile wallet. If you're holding real money though I would suggest spending on a hardware wallet and learning how to use it properly.
If you have any questions I'll try to help. As

mentioned there is a lot of complexity and it can be overwhelming. The basics are easy though. If I had to narrow the above down I would say just do Blue Wallet. Its simple and has support for most of the stuff you'll want to do.
