Maybe this isn't the best place to ask this, but I'll try anyway:

I'm a consultant involved in cybersecurity who often has to build and run VMs to either test out software, run things in sandbox, or connect to TOR from a VM I'll never use again.

Having said that, I currently use Windows with VMWare Workstation, but I find it frustrating and would prefer something that's less frustrating and feels more built-in.

Is there a solution that anyone would recommend for this kind of thing? Internal networks, Windows and Linux sandboxes, etc. I use Microsoft office products regularly, and my workstation (Dell Inspiron with an i9, 64GB ram, 2tb SSD) is connected to a thunderbolt 4 dock with 2 1440 monitors. I'd prefer for a Windows VM to have passthrough to the monitors and be able to interact with the host OS via that VM, so I can still share my screen during meetings and while coordinating efforts.

I don't known of this works with all your criteria, but you might want to go with UnRaid or Proxmox or a Type 1 hypervisor like vSphere/ESXi or Xen.

I don't get the distinction between type 1 and type 2.

E.g. xen is type 1 and KVM is type 2. But at the end of the day it's a Linux kernel in both cases that runs the virtual machines, so what's the point of distinction?

It's what runs above the vms that is the distinction. For xen it has its own kernel instead of running Linux as the hypervisor and host system. Xen still uses Linux typically as the domain zero as it calls it for doing control and setup but it doesn't necessarily have full access to all the hardware on its own.

I can't find information online. Does xen really has it's own, written from scratch kernel or is it based on some other os?

Completely it's own from scratch. It's a very simple, relative to full Linux or other OS, kernel/hypervisor. It's built to load what it calls the Dom0 system, which it gives a communication channel to to start up other virtual systems that it calls DomU. This in theory lets you use any OS as the Dom0 for initializing everything (Linux, *BSD, even Windows I think) as long as there's some kind of support for that communications channel to tell the Xen kernel to start up another system.
