I pretty much agree with all of that. AI selection should really be its own , user-friendly dialog. Maybe some options should even be selected before the lobby, during creation of the game in the FAF client dialog or with a specific "Create Game" button made for PvE (or maybe even an entire PvE focused page).

I don't see a reason why you would exclude turn-based strategy, and Civ 6 alone is played more than whatever 5 smaller games i could come up with. Then we also have Grand strategy and 4X genres that generally tend to not have campaigns. But i don't think listing games will imrprove this discussion.
What is your argument?
Its good for games to have a campaign? I absolutely agree. Players like to play campaigns? I agree. FAF should make playing the campaign a good experience? I agree.
However, in a campaign the players play against a mostly static setup predefined by the campaign authors. Campaigns tend to be not very replayable. "Free play", "Skirmish" etc. is were players are finally given the options to customize their gaming experience, and were games start becoming replayable. It is also were one-time campaign players might be converted into long-time FAF enjoyers. Regardless of the topic of campaigns, which i too very much enjoy, i do think that skirmish vs-AI should not be an overlooked gamemode.
