Just follow Terrible Writing Advice's guide to steampunk, that's what it's there for.
Ok seriously, I think most of the best steampunk stuff I've read keeps the steampunk kinda lowkey. When it starts getting too carried away with steampowered everything modern just steam it gets kind of unbelievable and ridiculous. Trains and boats did a pretty good job for a long time do we really need steam powered jets? And I think it helps to ask why steampunk? Even when it's just for aesthetic reasons, I think why that aesthetic?
For instance, slightly different but similar, while Clockwork Planet's clockpunk went a bit far with the future tech but clockwork sometimes, it was all about cogs and gears because it was leaning into a lot of clocksmith/clock metaphors with interconnecting cogs and gears of government and conspiracies that make the world go round figuratively and literally, and because it also leant into those periods of enlightenment and the mixing of unknown science and discovery but when people were still pretty superstitious (or maybe I put more thought into that than the creator and it was purely because clockwork is cool).
