What Should I Play?

Have you looked into Strike! RPG? Setting agnostic tactical combat on a grid heavily derived from dnd 4e but with all the fat stripped, leaving a very light, low-math, simple to run combat with a ton of depth but low number crunching. All that is paired with a narrative system that's very intentionally kept light and with intent to get out of your way.

If you're looking to run something where the PCs are a crew of specialists with distinct roles, this might be worth considering.

Going to recommend City of Mist to you as well.

Was a while since I played any Fate but if memory serves (think it does after a quick googling) a key part of it are aspects. And those are cool. 13th age' one unique thing and skill system can also be seen as tags. City of Mist, a thicc and chonky PbtA, also uses aspects but they call it tags. The hefty book is both setting and really many words about tags, how to use then and how to get more. For a PbtA system it is teally mechanically dense. I really like it but nit the setting. Lyckily they are working on a mythic cyberpunk adaptation of it and there have for a long time been talk of coming out woth a generic toolset.
