Looking for recommendations for tactical games

Hey there! I recently beat some XCom games (only 1 and Chimera Squad, 2 won't work on my potato laptop) and am looking for some more tactics experience. Therefore, I'll ask you to recommend me some games.

The first aspect of what I'm looking for is customizability. I have played some games, mostly on mobile, that were just series of scenarios tied with a story. No growth, no new tools, no individuality. I felt it was really boring. Progression between missions is great, unlocking new units/weapons/whatever. Also, being able to start the same mission and approaching it in 2 different ways, or more, feels great too.

The second aspect is the tactical focus should be there. It mainly refers to games like Age of Wonders, that do have a tactical fight layer, but it's a significant undertone to macromanagement of the whole kingdom. I don't want to knock games like this off, but I don't have enough energy to play games like this.

The third aspect is... the game should be hard, but not too hard. Roguelites for me are nice for that reason, as they're basically as hard as far you progress and there's not much threat of losing progress, like in Into the Breach you just start a new timeline. But it doesn't have to be a roguelite, and it doesn't have to be super difficult either.

The fourth aspect is fairly low hardware requirements. A lot of these games are turn-based, so it's theorerically less of an issue, but X-Com 2 was in 10 FPS for me. Painful, even when the game is in turns. There are games that work surprisingly well, like Chimera Squad (which is on the same engine 2 was, but for some reason was fully stable on minimum details), but still.

I'm not sure which game would be perfect in these requirements, but if you want here's an example of a game that fulfills almost none
