No. Qubes is slow and will make your CPU fan go burrrrr all the time. For your case, pick any distro and use hardened Firefox.

I take ityou've never used Qubes?
A few years back I've installed it. I doubt it's gonna run well on NCU.
Qubes 4.1 ran fine on my NUC when I had one. If you have ≤ 8GB of RAM, you'll probably want to limit the number of apps open to maximize performance (same as any other O/S).
Qubes will be about 98-99% as fast as any Linux distro. Qubes will run faster than Windows 11. This is because of the VT-x instruction set.
In case anyone is wondering, AMD has AMD-V which is their version of Intel's VT-X so you'll have the same performance with AMD whether using VMs or not. ❤️
I'll test it out when I get the chance. I like AOSP approach more.
