Reproduction steps

• Start Emacs

Open a C++ file. Go to a line. Press o.

Expected behavior

I want it so that it either inserts a tab (size: 4) in the next line or 4 spaces.

Actual behavior

Inserts 2 spaces.

Further notes

Noob tries to do stuff with tabs. Why is this so difficult.

; START TABS CONFIG
;; Create a variable for our preferred tab width
(setq custom-tab-width 4)

;; Two callable functions for enabling/disabling tabs in Emacs
(defun disable-tabs () (setq indent-tabs-mode nil))

  (setq indent-tabs-mode t)

(setq whitespace-display-mappings

; END TABS CONFIG

I am using evil-collection and evil. I have no clue what to do. Read manuals but cannot wrap my head around which option to set/unset.
