Or tell the system how many DPI my screens have, so fonts have the proper
physical size.

System settings → Screens → Global Scale
It uses a percent scale just like MS Winblows. But a percentage is always a

stupid) thing that MS did in their settings; scaling with a percentage with
no physical meaning behind it.
