well there's actually a lot of these kind of games now...
cliff empire, a cheapo city builder
foundation, a medieval city builder, on early access
kingdom and castles, city builder + combat element like stronghold
there are billions, survival tower defense + rts + rpg
surviving mars, martian city builder
northgard, viking age of mythology like rts
banished, medieval survival city builder like frostpunk
ancestors legacy, a medieval CoH, not to much depth in this one though
syrian warfare, hardcore tactical rts like men of war but in syrian war, this one is very deep in the tactical mechanics... but it has not so high production quality -aka low budget indie, from russia nonetheless
- so it's not as polished as MoW/CoH/WiC
wargame red dragon, the last iteration of wargame series
zero-k, a literally free to play supreme commander/ashes of the singularity "clone"
if you want management sim games there are games like factorio, 2.0 hospital, planet coaster, rise of industry, etc... there are a lot of these games nowdays, there's still plenty if you want to include RTS grand strategy, TBS, etc...
