TL;DR - About switching from Linux Mint to Qubes OS from among various other options that try to provide security out-of-the-box (also discussed: OpenBSD, SculptOS, Ghaf, GrapheneOS)

Not only is it resource‑intensive, but Qubes also lacks Secure Boot and Wayland support. Secure Boot is critical to ensure the OS has not been tampered with, and Wayland is required to isolate individual apps running within a single VM from capturing input intended for other apps. For an average user, I would recommend SecureBlue rather than Qubes.
Qubes OS has an Anti-Evil Maid option that is far, far better than signed boot.
AppVMs are isolated in Qubes even without the help of Wayland
