Give Qubes OS a shot. It's significantly less challenging to run than it used to be, and a (small, I admit) number of us daily drive it. Hardware support these days, while far from perfect, is much better. It's not the daunting slog to get it going that it used to be.

Provided you aren't looking to run accelerated graphics or care about integrated Bluetooth, you should be fine. I'd recommend any Intel laptop (and some AMDs) with built-in Ethernet, just in case it doesn't like the Wi-Fi card. Install with kernel-latest (it's a simple option when you boot into the installer ISO), and try it out. Grab a T480/T480s if you have one handy, and you may be surprised.
