I'm seeking RTS games with Pause function where units can still be commanded for a more chill experience.

I know that pausing in an RTS (REAL time strategy) games are a bit counter intuitive, but i'm a person who gets very easily overwhelmed and very easily stressed these days. i USED to not only enjoy RTS games, but play them a lot. But I find myself far more easily stressed out by them.

Been looking for a few RTS games to go through, where I can still command the units when i pause the game.

I have vague memories of older titles from 1990s allowing this, but more as an unintended feature.
But i don't remember which ones. I just remember it vaguely possible.
Maybe Earth 2160?
Lots of RTS games, just a matter of which ones offer the ability to pause the game to allow me to stay ahead :D
Maybe Dark Reign? I remember playing this a boat load, but i don't remember if pausing the game was possible, let alone still commanding ones units when paused.

I don't care about multiplayer. Just looking for Campaign & Skirmish modes.

EDIT: A big list of suggested game thus far, in no particular order:

Total War + Napoleon and Empire -- See this recommended a few times.
Total War: Warhammer 3 -- Maybe, maybe.
FTL -- I have gotten tired of the game loop, moving on.
Convoy -- Apparently like FTL, but a new take? Might give it a go!
Doorkickers 1 & 2 -- Remember seeing this a while ago, was very very interested, forgot to wishlist. Not this time!
They are billions -- Looks very very fun, but not sure if the price justifies it. Others would say it does. Hmmmmm...
Diplomacy is Not an Option -- On my wishlist, been for a while. Looks very fun too.
Sins of a solar empire 2 -- I'm convinced i tried a pirated copy of this, i liked it, but then forgot about it? It's on my wishlist for sure!
Total Annihilation series: Supreme Commander, Zero-K and BAR (Beyond All Reason) -- They all offer something slightly different, but are all born from the design of Total Annihilation. All good games with their own spin.
Homeworld Remaster -- Been eyeing this game for a loong time, not sure it's my cup of tea.
Homeworld: Deserts of Kharak -- Never heard of or seen, will have to investigate more.
Company of Heroes 3 -- Maybe, Maybe.

Last Train Home -- no clue, will take a closer look.
mindustry -- Made a few mods for this, got 80+ hours on it. Lovely game. Can quickly kick your butt if you aren't careful. Sneaky difficulty sometimes.
Command and Conquer franchise -- I never knew it had a pause mechanic that still allowed me to issue commands. Will have to reply then!
Starcraft -- apparently allows you to also pause and command units, never tried. May try it again some day!
Starcraft 2 -- Last i heard it was MP only, so i never picked it up, but if it actually have a story, then i GOTTA get it!!

Shadow Tactics -- Unknown to me, will take a closer look.
Shadow Gambit -- Unknown to me, will take a closer look.
Warcraft -- Good old Warcraft. I remember putting in the CD the first time and hearing the music. Still gives me chills. Personally, i enjoyed Warcraft 2 more. But Warcraft 3 took it out of the park with RTS. It was just awesome!
age of empires 1 -- I think i'll go test the pause feature, could be cool to finally beat the campaign!
age of empires 2 -- While i knew it could be paused, didn't know i could command units, time to beat campaign :D
