I am noticing recently that there is a strange input delay when typing on the keyboard.
Typing feels responsive, however every few seconds there will be an input lag, it appears to happen at regular intervals and severely affects the typing experience.

I don’t use any kernel flags, but do use powertop defaults and tuned-ppd as AMD and Fedora prescribe.

I am not sure if this is expected from the Framework, or Gnome 47.
Has anyone else experience this lag? Or could it be something to do with how power management is handled by powertop? Should certain acpi settings be set to “bad”?

Hi. I tend to leave the default ones that come as “Bad”, and leave them as “Bad”.
You can experiment with turning “Bad” to “Good”.
I suspect leaving the Keyboard module as “Bad” might fix your problems.
It also causes other unwanted affects, such as unwanted repeated keys.
