Yes
Anyway,
If you ever get bored of the one-note playstyles of some civs, try @p0kiehl's
Civilizations Expanded. It expounds on the abilities of every civs, expanding on some, tweaking others, and fully reworking a select few. In numerous cases, it opens up entirely new playstyles for rather static civs. And even in cases where their greatest strength remains the same, it's been doubled down on and pronounced, with additional strengths added to complement it. Just be warned: with some famously asymmetrical civs (Kongo, Gaul) it gets rid of their distinct restriction or weakness, meaning that they won't have the same interesting restriction. But for more by the books civs (like the personally boring France), the changes are a net positive. I don't keep it on in every game, but when I get tired of the unmodded Civ designs, it reinjects so much life and excitement into the game. Highly recommend.
If you're satisfied with civ abilities but disappointed by the same-old infrastructure, then I'd recommend JNR's
Urban Complexity mod series. It changes and reworks all of the existing districts and buildings, while adding numerous new ones to heighten strategic depth. Additionally, many of the changed/added buildings reward tall play and planning, opening up many new strategic possibilities and a treasure trove of synergies. Its effects aren't nearly as pronounced or game-changing as Civs Expanded, and you may end up feeling it can be a bit mundane at times. But once you start pursuing each of the complimentary bonuses of the buildings and pairing them with unique districts, it gets really fun. To try it out, I'd recommend a Pangaea game with Rome. The aqueduct gets some interesting changes in Urban Complexity (to the point where it's now called the Cistern instead), meaning that Rome feels some pretty pronounced effects with this mod. I haven't fully explored it myself, but I bet you'll enjoy it. (also, check out some of JNR's other mods. They have a lot of cool general tweaks)
Lastly, if you're looking for more city specialization, then
City Lights is probably the mod for you. This mod forces cities to choose between being Rural (designed to be small and self-sufficient, with few districts and lots of basic tile improvements) or Urban (large, tall, yield powerhouses that love districts but have no tiles to make their own food and production), resulting in a heightened importance of domestic trade to transfer yields throughout your empire. There isn't really anything more to explain here, so whether or not you're sold on the mod depends on if its core idea hooks you. I don't have a ton of experience with this one either, but it rewards you heavily for planning things out, even if it does result in a tiny bit of gold inflation.
(Oh, and take a look at
what Eps has to offer to see if any of their small tweaks interest you)
