A correct solution is to remote into instances on dedicated (bare metal) servers (use ECC memory and SSH with a good cipher for your transport, even across your local or VPN/WireGuard.. network!), perhaps using KVM/QEMU for macOS VMs (yep, requires a MacPro to be legal) and KVM/Firecracker for Linux VMs. You could do Windows VMs in KVM/QEMU, but will have less friction remoting into an alternate (HyperV) box for that (using Windows-specific security products). RDP-over SSH for Windows, MPEG-VNC-over-SSH for macOS (and Wayland).

Why? Did you checkout the Privacy Policy for Parallels? The last time I checked, it allowed them to remotely take anything from your systems that they want. If I wanted that, I would just use a VPS running on someone else's machine in a cage somewhere.

VMware, by the way, is now Broadcom, as in they reportedly replaced the staff and ripped up the perpetual licensing model (subscription only now)... Even before that, the Fusion product development had been shifted overseas, presumably to avoid paying higher wage software engineers in Silicon Valley (what a brilliant way for a software company to innovate) --now a company in Singapore is wearing their skin and the C-suite are out of jobs too.
