I'm going to offer up some good stuff for the setting(moreso tips for players):

Instead of computers,  one works with "analytical engines"


In steampunk fiction,  the aesthetic is often emphasized, so be sure to describe things and their functions/operations,  even if we're leaning more into the fiction than the science.  The same goes for fashion,  definitely lean into the style,  and the cultural mannerisms,  even if the society is presented as more egalitarian/modern than what might be considered accurate to the period one is emulating. Basically,  the genre lends itself well to "padding" :P

the aether angle can accommodate some tech and devices otherwise not possible when limited to steam and clockwork; take advantage of that! Like the OP said,  you don't feel constrained to the limits of hard science,  it's not science fiction it's science fantasy  :P

And if I'm stepping on toes do tell me to back off
