Dragonflight campaign after boosting problems

I boosted a my main character a while back in season two. I also just did the enhanced boost you get from preordering the next wow xpac on a alt, and received 20 renown giving my main the “Word of a Worth Ally” buff to all basic factions in dragonflight(Dragonscale, Maruuk, Iskaara, and Valdraken). I want to get all renowns maxed on my main via the campaign and side missions for each area but cant seem to be able to find any. did my boost from season two auto complete the main campaign and reward me with nothing? Will i have to resort to mindless daily/weekly farming to achieve max in each renown?
