I have over three decades of experience as a CPU architect.

Spectre and Meltdown are problematic for computers that run untrusted code, and then extracting secret information is a slow process because the attacks are based on timing. On client machines, running untrusted code usually means that security is already broken.

Your posts have so many misconceptions that it is not worth my time to respond to them.

The bottom line is that when one buys a computer, one is trusting the hardware manufacturers (including any firmware that they supplied). Running an open-source OS does not preclude the need to trust the hardware manufacturers.

What about consumer devices like modern TVs?

I don't have an issue with peripherals. Debian is ok.

I'm asking which cpu is best for debian on a new pc-build.

Only if you update the BIOS/UEFI to the latest version. However, as stated in the debian page the manufacture may not provide release updates just for microcode and they will stop supporting that particular motherboard at some time.

Thank you - this means I must rely on the debian microcode upgrades.
And they will not upgrade unless I have contrib and non-free in /etc/apt/sources.list.
A debian main-only is no longer possible.

Perhaps debian should update its documentation?

As previously stated just don't use the contrib and non-free repositories...

Why? The debian micocode will not install properly.

True, Wikipedia is not the end all for all the facts but do read
