You could try the Valkyria Chronicles series, I'm quite fond of them. It has an anime style, so if that isn't your thing...
Battletech is a good one if you like giant mechs
Phoenix Point. Man, I want to recommend this, but I will say buy it on sale.
Othercide is a hardcore roguelite "Xcom" game. I love it, but I can see how it would be rage-inducing.
Fort Triumph is a good try for a fantasy version. get used to hitting people with terrain, though.
Last one: Phantom Doctrine. Cold War era, launched in an unfortunate state, BUT has improved appreciably over time. Again, maybe wait for a sale
Hope this helps, strategy and tactics games are some of my favorites
