My only tab-related init.el config is:
(setq-default indent-tabs-mode nil) ;; indentation can't insert tabs
(setq-default tab-width 4) ;; make tab-width 4 (spaces)
but in c-ts-mode I have that the indentation only does and works with 2 spaces (I need to indent-region whole file otherwise to fix it). How can I make this back to 4?

For that you can check out the reformatter package, which lets you setup hooks based on the programming mode to invoke the formatter of your choice, e.g. setup a hook for c/c++ to use clang format or whatever you’d
c-basic-offset did not work. that was the first thing i tried.
