Came to crypto because of altcoins, here to stay because of Bitcoin.
Coldcard is a solid, bitcoin only commercial option. If you don't mind a little DIY then Krux or seedsigner might be a good choice too. You can also make your own with an old laptop. Remove the WiFi functionality (rip out the board or antenna) and upload Linux. Install a wallet on there like electrum or sparrow (transfer it over via usb) and you have an airgapped wallet.

Coldcard post anti-forensics for paranoid people
As you can see, the default firmware of Coldcard is hardcoded with values d13e and cc10. We are going to change it to make it look like a benign USB device, more on it later. First, clone the original firmware from Github: https://github.com/Coldcard/firmware We now need to edit the file called ./stm32/COLDCARD/shared/usb.py: COINKITE_VID = 0xd13e CKCC_PID = 0xcc10

Is it safe to buy bitcoin on a fidelity account?
Coldcard has many other security features as well. You can find more about them online. Probably the safest hard & cold wallet on the market right now. But most people don't buy it because of their $400 price tag. But definitely worth it for anyone holding more than a pretty penny.
