I know about Xcom, Jagged Alliance 2, 7.62 High Calibre, Banner Saga, Battletech, and Shadowrun. I look tactical rpgs up on jewgle and all I get is animu. Just give me a "what to play" list.
I don't count underrail because you only control one character (still one of my favourite games).
I don't like anime all that much myself, but
Troubleshooter is a great game with excellent tactical combat (a mixture of nuXCOM and Final Fantasy Tactics) and a meaty build system. It's also huge, with tons of new systems introduced as the story develops (e.g. several kinds of pets, crafting, etc.), with at least a couple of hundred hours worth of gameplay if you're up for it and get into it. The story is told in manhwa (Korean manga) form (and it's actually pretty decent - restrained and charming, not hyper-exaggerated in style), but the actual battlefield gameplay is just your standard quasi-realistic nuXCOM look.
I'd also recommend
Phoenix Point. It's a flawed game that's not as great as it could have been, but doesn't get as much exposure as it (now) deserves. It's marketed as a nuXCOM like, but it's much more of a sim, with an aiming system and bullet physics system that changes the tactical vibe of it quite a bit from XCOM, making it very much its own thing. (Don't activate the air combat DLC on your first run though, it's a bit wonky).
Dungeons of Nahuelbuek is also deceptively simple, but actually quite engaging tactically, with great use of directional facing and adjacency support.
If you want more of an s-f vibe, try
Stellar Tactics. It's an indie one man band, and a bit rough and still unfinished, but the ground combat is quite addictive at the tactical level, while the space combat is more arcadey, and the space exploration very open world.
