Bartholomew's 'climbing the rating ladder' content is at a similar level if you've finished with Naroditsky but I think Chessbrah's 'Building Chess Habits' speedrun is even better for most people. In that one GM Aman sets very simple ways to play and doesn't deviate from them even if it loses him some games while climbing or if there are obvious tactics he can use for a quick win. Naroditsky while great will often go into lines that a lower rated player is very unlikely to see or pull of and is very often winning out of the opening by knowing all the moves to punish suboptimal moves which lower rated players won't know.
