I agree with you. Web design doesn't seem to be the strength of the Whonix team.. and got worse over time.
Basically, you download a Virtualbox image, import it and then have a hardened Debian VM with Xfce UI & some privacy-friendly apps like Tor browser & a crypto wallet. The internet is slow (because of Tor) & tcp-only, but sufficient for most things. Virtualbox guest extensions are included and most things work out-of-the-box.

Only through Qubes, but I do most of my web access in a disposable (ephemeral) Whonix VM in Qubes, and it does exactly what it says on the box.
Whonix (KVM) is like running Debian with XFCE, but no matter what you do, your real IP address will never leak, at any point.
Click "What Is Whonix?", scroll down, "Whonix ™ consists of two VMs: the Whonix-Gateway ™ and the Whonix-Workstation ™. The former runs Tor processes and acts as a gateway, while the latter runs user applications on a completely isolated network."
